Introduction
Several studies have explored the genetic recombination catalyzed by cell-free extracts of Escherichia coli exploiting the tiny globular DNA genomes of plasmids to understand the mechanism of DNA recombination and familiarity with the products produced. The evidence currently existing on the recombination of DNAs arises from several experiments that have analysed recombination products using genetic methods or that have determined the structures of recombination products and intermediates using physical methods. According to Tüzmen et al. (2018), R-DNA technology opened up a brand-new era in scientific study. Molecular cloning, a new development in molecular biology, allows for the creation of DNA sequences not typically seen in biological organisms by combining genetic material from other animals. These rDNA molecules are produced in the lab using methods like molecular cloning. These foreign rDNA fragments are transferred to and expressed via vectors in suitable host organisms like bacteria. Rearranging segments of DNA, frequently between homologous areas, is known as DNA recombination. With the advent of DNA shuffling technology in the last ten years, this process which occurs in natural evolution, has been utilised for combinatorial protein manufacturing. (Ducheyne, 2015).
Plasmids are typically circular double-stranded DNA molecules covalently closed, similar to bacterial chromosomes. These self-replicating additional DNA fragments allow their hosts to adapt to environmental obstacles or specific niches by expressing certain genes. Genes carried by plasmids are generally optional, but giant plasmids, called “chromids”, frequently carry genes crucial for basic physiology. Plasmids also aid in the horizontal spread of the genes they carry, frequently between different species, which aids in the process of evolution (Million-Weaver, & Camps, 2014). Several DNA substrates are required depending on the application. The development of suitable single- and double-stranded linear targeting substrates for various uses. Recombination of DNA A section that has to be inserted is surrounded by two homology arms and is known as the linear dsDNA substrate for recombineering. The inserted area could be a counter-selectable marker or a non-selectable DNA used in its place (Sharan et al., 2009).
Simple DNA recombination in vitro was initially made possible by DNA shuffling. A collection of homologous genes serves as the beginning material, such as a random mutagenesis library produced by PCR or genes from closely related species or families. It is possible to purify plasmid DNA by separating it from chromosomal DNA after obtaining DNA from a strain that includes plasmids. If the plasmid contains a single, unique target site for enzyme, restriction endonucleases produce linear plasmid molecules with brief complementary single-stranded sequences at each end, also called “sticky ends,” by cutting the double-stranded DNA asymmetrically. The DNA that has to be inserted is likewise subjected to an endonuclease treatment that yields fragments with comparable sticky ends, enabling annealing between complementary sequences to occur when the plasmid and insert DNA are combined under the right circumstances. The enzyme ligase creates the covalent linkage between the insert and the vector DNA (Hussey, 1992).
Plasmids are kept stable inside the host bacterial cells by several processes. Plasmid dimerization creates multimers, decreases the amount of molecules in the cell and also cause instable plasmid segregation. Plasmid stability is guaranteed by the site-specific recombination machinery known as Xer, which catalyses the breakdown of plasmid dimers into monomers. The resolution of chromosome dimers, which enables appropriate segregation of chromosomes during cell division, is another function of this recombination mechanism. By facilitating the integration of phages carrying genes encoding virulence factors, it is also indirectly engaged in virulence (Bui et al., 2006).
Recombineering has many applications due to its high efficiency and minimal homology needs. Selectable or non-selectable markers can be inserted into plasmids and bacterial chromosomal DNA recombination. To generate alleles in embryonic stem cells, they can be used to produce constructs for gene-targets (Sharan et al., 2009). It is an efficient way for extensive research that requires the expression of thousands of genes as proteins. Due to the exceptional requirements and provisions of each construct, conventional cloning techniques based on restriction enzyme ligation and digestion are not practical. High-throughput cloning of genes into protein expression vectors is possible without restriction digest procedures using recombinational cloning, which moves DNA from one vector to another based on sequence homology. Site-specific recombination is employed in DNA recombination when the vector and insert both have the required sequences of nucleotide for the cloning enzymes for the identification of recombination process. They are known as “recombination sequences” because of their nucleotide specificity. Recombinational cloning also has the benefit of enabling the creation of entry clones. A single insert can be transferred into many expression vectors using this intermediary clone, which also acts as a holding or store clone. In order to create a particular type of library, numerous entry clones with different sequences can also be put together in a single expression vector (Throop & LaBaer, 2015)
Escherichia coli has advantages over other host organisms for in vivo DNA assembly, as well as faster growth rates, large amount of plasmid, and improved efficiency of transformation. In vivo DNA assembly techniques in E. coli have been developed due to several investigations (Kostylev et al., 2015). In order to produce heterologous gene products with both prokaryotic and eukaryotic origins, bacterial expression methods are frequently employed. E. coli, a bacterial system, is most frequently and regularly utilised for expressing heterologous proteins. Nowadays, E. coli produces a variety of heterologous proteins with medicinal importance. Human insulin made in E. coli and initially licenced in the UK, West Germany, The Netherlands, and the USA in 1982 was the first heterologous protein used in clinical practice (Fakruddin et al., 2013). This study’s main goal was to identify three different stains’ changes on the plasmid DNA when cells are cultivated in them. It also describes how to examine the byproducts of plasmid recombination events using plasmid substrates that carry physical and genetic markers.
Methodology
Three different E. coli strains, i.e. DS941 DS941 regular cloning (LB), DS945 dimerization (LB), and FC33/pSDC115, containing a plasmid with two cer-site, were used in dimer resolution assays. Plasmid pUC19, needed for cloning and as the negative control in all transformation steps, and pSDC115, required as a positive control, were utilized in this project.
Miniprep
The first step of DNA recombination included the restriction digestion of pUC19 with EcoRI and HindIII. Plasmid DNA was obtained by the QI prep kit using a miniprep technique. The QIAprep miniprep technique’s plasmid yield varies with the number of plasmid copies per cell. The specific insert in a plasmid, aspects that influence bacterial culture development, the volume of elution, and the length of the elution incubation time it was employed right away after they were purified to remove plasmid DNA (Kit et al., 2002). We set up three different reactions for pUC19. Bacteria that had been pelleted were re-suspended in 2 μl of buffer p1 and then put into a microcentrifuge tube. A check was made to see if RNAse had been introduced to buffer p1. After adding it, the 2 μl buffer P2 solution was well mixed by gently flipping the tube 4–6 times. The 2μl bufferN3 solution was added, and a homogeneously coloured suspension was formed. Centrifuged the mixture for 10 min at 13,000 rpm. Afterwards, the solution was run through the Qiaprep 2.0 spin columns before the vacuum source was turned off. The dry DNA was dissolved in 15 μl of sterile water and placed on the bench for at least one hour at room temperature. Then, the sample was digested with HindIII+EcoRI (1 μl of buffer, 5 μl of DNA, 1 μl of diluted HindIII, 1 l of diluted EcoRI, and 2 μl of water). The solution was then incubated at 37 degrees for one hour, followed by 10 minutes of heat inactivation at 65 degrees. The double-digested product was then put onto the gel for gel purification. After the digestion of the pUC19 plasmid, we made an agarose gel, and the GelRed was added to the agarose. The elution was made under UV light to ensure we had enough DNA.
Preparation of agarose gels
E.coil strains were produced, and then 0.8% agarose gel was made. The fragments are viewed using an agarose gel. DNA molecules can be separated using this technique between a few hundred and over 10,000 nucleotides in length. The gel equipment was filled with molten agarose. Next, the bench was covered with agarose gel. After the agarose had dried, 50 ml of gel was poured over it while still running with buffer (TBE).
Gel electrophoresis
Gel electrophoresis was performed on 0.8% agrose gel. Extracted cDNA PCR products and their negative controls were run on an agarose gel to distinguish cDNA strands.
Preparation of Azure solution
0.4g Azure A chloride solid was dissolved in 500mL 40% Ethanol to prepare 2x Azure A. then the solution was stored in a glass screw-capped bottle out of direct sunlight. The solution was diluted with distilled or deionised water to a desired final volume.
Staining with Azure solution
Transfer the gel to the plastic box after pouring out the buffer solution. Fill the container with enough 1x Azure A solution (0.04% Azure A in 20% ethanol) to completely cover the gel. High-concentration DNA bands were seen at this point, 10-15 minutes after staining. DNA of the proper size to be a plasmid dimer was recovered from the electrophoresed plasmid DNA in a 0.8% agarose gel.
Gel extraction
The same procedure was used for gel extraction after staining with Azure as used in Ethidium bromide gel extraction without using a UV transilluminator and related face protection. The only difference was the results from using Azure A are a color change that is not typically observed when using the kit. We weighed the gel slice in a clear tube after removing the DNA fragment from the agarose gel. One volume of gel received three volumes of buffer g. 400 mg of gel might fit into one spin column at most. It was incubated at 50°c for 10 min. Then we Vortexes the tube every 2–3 min to help dissolve the gel. After the gel slice had utterly dissolved, we added one gel volume of isopropanol, mixed it, and then quickly spun a column in the 2 ml collecting tube. After applying the mixture to the QIAquick column for DNA binding, the mixture was centrifuged for one minute. Put the QIAquick column back into the same tube after discarding the flow-through. After cleaning the column, 750 l of buffer was added to the QIAquick column, which was centrifuged for one minute or subjected to a vacuum. The yield of pure DNA may increase if the incubation period is extended to 4 minutes using a QIAquick membrane.
Preparation of LB broth and LB plates
We prepared the LB or LB/agar bottle, and Ampicillin was added to the LB plates.
Ampicillin stock
1000X Ampicillin stock, 100mg/ml, was prepared by dissolving 0.5g of ampicillin in 5 ml of distilled water. A vortex was stirred to ensure that all the powder had been solubilised in the solution. And then sterilised using a 0.2nm filter.
Preparation of competent cells
5 ml of LB medium inoculated with an overnight culture without antibiotics. Then 25 ml of cells were added to two 50 ml sterile falcon tubes before transferring the cells and incubated. The mixture was on the ice for at least 20 minutes. The supernatant was discarded after centrifuging for 10 minutes at 2700 rpm and four °C. Each pellet was carefully suspended in 25 ml of ice-cold CaCl2-MgCl2 solution. Throw away the supernatant after a 10-minute centrifugation at 2700 pm and four °C. The cells transformed after being carefully suspended in 500 l of ice-cold 100 mM CaCl2 solution.
Transformation of E.coli cells
For the transformation process of cells, three different aliquots of DS941 were prepared, i.e. first with 10ul of the ligation reaction, second with 3ul of pUC19 and third with 10ul of sterile water. After gently stirring, the mixture was incubated on ice for 30min, then given a heat shock at 42°C for 45s in a heat block. After this step, 400ul of LB was added and incubated at 37°C in the shaker for one hour. Then the cells was diluted and plated. A total of 6 LB/Amp plates with antibiotics and 3 LB plates without antibiotics was used for transformation
Ligation
For ligation, we set up the following reaction
2 μl ligase buffer + 8 μl purified HindIII/EcoRI pUC19 + 8 μl HindIII/EcoRI insert + 1 μl water + 1 μl T4 ligase
The reaction was mixed by pipetting gently, then the mixture was incubated at room temperature for 10 minutes. Then 65 °C heat was used to inactivate for 10min in the heat block. Ice was used to cool the mixture, and 1 to 5 ml of the reaction was converted into 50 ml of competent cells.
Results:
Several strains of E. coli were created using plasmids. From the resultant transf0rmants, plasmid DNA was isolated, and the DNA fragments were determined by electrophoresis in agarose gels. To avoid artefacts brought on by recipient strain transformation by oligomer contamination of monomeric DNA extracted from strains in these investigations, monomeric DNA had to be gel-purified. DNA that had been isolated from several different transformants was analysed to gauge the impact of variation.. Three different E. coli strains, i.e. DS941 DS941 regular cloning (LB), DS945 dimerization (LB), and FC33/pSDC115, containing a plasmid with two cer-site, were used in dimer resolution assays. Plasmid pUC19, needed for cloning and as the negative control in all transformation steps, and pSDC115, required as a positive control, were utilized. After filtering and incubation with calcium chloride we take the readings that were, Reading 1 0.272 Reading 2 0.327 Reading 3 0.379 Reading 4 0.420. these are readings depend on the concentration of the calcium chloride.
Using aseptic techniques and sterilizing the environment, cells were taken from plates and transferred to universal bottles containing LB broth. Moreover, the same amount of ampicillin was added before moving the cells.
Figure 1 (a) : DS941 grow on LB plates in the presence of Ampicillin plates for ligation, puc19 and water.
Figure 1 (b): LB plates without ampicillin of water for DS941.
Figure 1 (a) showed that cells DS941 grow on LB plates in the presence of Ampicillin plates for ligation, puc19 and water. Figure (b) showed that cells DS941 did not multiply on LB plates in the presence of Ampicillin plates for ligation, PUC19 and water.
PUC19 is ampicillin resistance therefore it shows grow on the LB plates. The plates were checked and inoculums for ligations of FC33, PSDC115, DS9456 and DS9457 were made Protocol for mini preparation showed the band for the plasmid, and the PUC19 gel image below showed ligation and PUC19 alongside with DNA ladder.
Figure 2: The gel image above shows ligation and PUC19 alongside with DNA ladder.
The sequence is as follows
LANE1- DNA ladder
LANE2- PUC19
LANE3- Ligation1
LANE4- Ligation2
LANE5- Ligation3
PUC19 control DNA is provided to check transformation efficiency. After the transformation, cells were diluted, plated, and left in the incubator for overnight growth. Our results results showed that DS945 cells shows no grow in the presence of LB/Ampicillin of PUC19, Ligation and Water. At the same time, DS945 cells show growth in the presence of LB plates without ampicillin or water plates. For a number of reasons, the maximum specific growth rate (max) of recombinant strains is crucial. Of course, production will be more effective when biomass formation is quick, but even more crucially, growth rate retardation brought on by plasmid maintenance appears to be a contributing element in segregational instability and has critical implications for risk assessment.

Figure 3 (c)These images shows growth on LB plates without ampicillin of water plates for DS945 cells.
The electrophoretic analysis of plasmid DNA preparations presented below in figure 4 distinguish between dimers from Lane2 PUC19 and Ligation(DS945) in Lane5.
Figure 4 electrophoretic analysis of plasmid DNA
The sequence is as follows-
LANE1- DNA ladder
LANE2- PUC19
LANE3- Ligation1
LANE4- Ligation2
LANE5- Ligation3
The first lane is DNA ladder from which the other molecules was separated based on their size and charge. shorter pieces of DNA traveled through the pores of the gel matrix faster as lane 2, which shows PUC19. Lane 3, lane 4, lane 5 showed that ligation 1, ligation 2, and ligation 3 which negatively charged are near the wall. We failed to transform the DS941 PUC19 and PSDC115 strains with pRDKl01, perhaps as a result of the combination of the relatively ineffective transformation process, a strain of E. coli that grows slowly, and the absence of ampicillin. In general, PSDC115 monomers reacted similarly to FC33 and DS956 monomers, with the exception that PUC19 DNA and DS941 typically generated larger quantities of Diemers. In FC33 and DS956 strains, monomeric did produce detectable quantities of dimers for PSDC115.
Figure 5
This gel image in figure 5 shows
LANE1- DNA ladder
LANE2- DS941
LANE3- PUC19
LANE4- PSDC115
We numbered the four lanes above the gel, by comparing the other band band with DNA ladder we will determine their approximate size. In gel, lane 1 which showed DNA ladder, that is the well defined fragment in the gel. Lane 4 which is smaller in size than lane 4 and contains PSDC115 and PUC19 fragment are moving faster in the gel then the fragment present in lane 2. PSDC115 showed one band, which means dimers have been converted into monomers. The agarose gel demonstrates that the plasmid’s mono and dimer forms have an identical restriction pattern, but the dimer migrates more slowly, as can be seen in lane 2. Each of the aforementioned evidence points to the possibility of ligation in monomer, dimer, and trimer forms. Furthermore, we noticed that even at low plasmid concentrations, most of the plasmid appears in solution as a dimer, and enzyme kinetic parameters revealed that dimer activity was considerably higher than that of mono or trimer, which likely has some biological significances.
Figure 6 gel image
Again the first ladder is the DNA ladder, in this gel the lane that is the ligated fragment of PUC19 PSDC115 as PSDC115 is monomer therefore it is smaller in size and moving faster in the gel. Lane 5 DS956, lane 6 FC33, and lane 7 PSDC115 are non ligated fragment therefore these are smaller in size.
Discussion
This study aimed to identify three different stains’ changes on the plasmid DNA when cells are cultivated in them. It also describes examining the by products of plasmid recombination events using plasmid substrates that carry physical and genetic markers. Recombineering is a straightforward, 50-base homology-based in vivo genetic engineering technique mainly employed in Escherichia coli. Although homologous recombination is the foundation of recombineering, it is independent of the position of restriction sites and enables exact insertion, deletion, or change of any sequence. Electroporation is used to introduce linear DNAs, either single-stranded synthetic oligonucleotides or double-stranded PCR products, and they provide the homologous substrates needed to make genetic modifications. The most popular host for the recombinant DNA technology used to produce enzymes and other proteins in E. coli. E. coli is preferred due to its relative simplicity, quick and affordable high-density production, well-known genetics, and plenty of available suitable molecular tools (Sharan et al., 2009). Three different E. coli strains, i.e. DS941 DS941 regular cloning (LB), DS945 dimerization (LB), and FC33/pSDC115, containing a plasmid with two cer-site, were used in dimer resolution assays. Plasmid pUC19, needed for cloning and as the negative control in all transformation steps, and pSDC115, required as a positive control, were utilized in this project. A high plasmid cloning vector called pUC119 was used to clone, replicate, and produce single-stranded DNA in E. coli. Single-stranded pUC119 DNA is produced as a result of helper phage; most of this DNA is bundled into phage particles before being released from bacterial cells. From a metastatic human lung cancer, an amplified human sequence was discovered. Several E. coli strains appeared to be affected by a segment of this sequence located behind the lac promoter of pUC19. A 369 bp fragment that appeared to cause anomalous plasmid supercoiling was discovered after subclones were built to determine the most minor portion of the human insert that conferred the activity. A surprising outcome was seen when several constructions were added to the minicell-producing strain of E. coli DS410 to examine this characteristic. Following their early, normal development, the bacteria clumped up in the late log phase, leaving the medium nearly transparent (Heighway et al., 1989). It is advised to use E. coli due to its relative simplicity, quick and economic high-density production, well-known genetics, and the abundance of appropriate molecular tools. Despite all these benefits, recombinant enzyme expression and synthesis are not always successful and can lead to insoluble and dysfunctional proteins. The success of cloning, expression, and mass manufacture of enzymes by recombinant E. coli is influenced by various variables (Fakruddin et al., 2013). Ligation, or even the joining of DNA fragments, is a crucial step in molecular cloning that is required for the creation of genetically modified organisms that can be employed for fundamental research, applied biosciences, or both. Because that so many genes collaborate in numerous pathways, it is frequently required to combine different genes cassette in a transgenic DNA construct for genetic alteration when creating organisms that generate numerous foreign genetic instructions (Takita et al., 2013).
In this experiment calcium chloride was used for transformation which shows the increasing transformation activity. According to another study Lim et al., 2015, thier findings, pUC19 is more likely than pBR322 to be affected by calcium chloride’s tendency to increase transformation activity. In particular, pUC19 has a maximum transformation efficiency of 2.5 times greater than pBR322. This data does not support their theory, which assumed that as the concentration of calcium chloride increased, the transformation efficiencies of pBR322 and pUC19 would be comparable. To ensure that their results on transformation efficiency can be compared to those of other articles of a similar kind, we based our analysis on the quantity of plasmid employed. Their model predicted that pBR322 needs more calcium chloride than pUC19 to achieve optimum transformation efficiency. They predicted that pBR322 needs more calcium chloride than pUC19 to achieve optimum transformation efficiency. This is because pBR322 is a bigger plasmid and needs more Ca2+ ions to balance the negative charges (Lim et al., 2015).
The experiment showed that that cells DS941 grow on LB plates in the presence of Ampicillin plates for ligation, puc19 and water. The ampicillin resistance gene is present on pUC119. From a metastatic human lung cancer, an amplified human sequence was discovered. Several E. coli strains appeared to be affected by a segment of this sequence that is located behind the lac promoter of pUC19. A 369 bp fragment that appeared to cause anomalous plasmid supercoiling was discovered after subclones were built to determine the smallest portion of the human insert that conferred the activity.
Plasmids are widely acknowledged as being the means by which a variety of genes are disseminated in bacterial populations. Recent research has shown that novel plasmids isolated from environmental bacteria are frequently not closely linked to plasmids of clinically significant bacteria that have been thoroughly described. The bulk of plasmid, despite their diversity, can only be classified into a small number of evolutionarily connected groups, according to comparative analysis of the Rep proteins produced by plasmid. The majority of plasmids encode rep proteins, which are crucial for the start of their replication (Kalyaeva et al., 2002).
A surprising outcome was seen when several constructions were added to the minicell-producing strain of E. coli DS410 in order to examine this characteristic. Following their early, normal development, the bacteria clumped up in the late log phase, leaving the medium nearly transparent. For a number of reasons, the maximum specific growth rate (max) of recombinant strains is crucial. Of course, production will be more effective when biomass formation is quick, but even more crucially, growth rate retardation brought on by plasmid maintenance appears to be a contributing element in segregational instability and has critical implications for risk assessment. Our results results showed that DS945 cells shows no grow in the presence of LB/Ampicillin of PUC19, Ligation and Water. At the same time, DS945 cells show growth in the presence of LB plates without ampicillin or water plates. . We describe a method for plasmid selection in E. coli that involves overexpressing a gene required for growth that gives resistance to a specific protein blocker. Without ampicillin, PUC19 showed improved growth, yield, and gene containment in addition to a decrease in the use of drugs and genes that cause antibiotic resistance. These developments appear to be caused by the mechanism of inhibition and a balance of detrimental gene-inhibitor levels required for cell survival and selection. Similar connections suggest that reciprocal inhibition between gene inhibitors may be a common mechanism in other systems (Goh et al., 2008). Because it can be utilised to boost plasmid copy number and yield, the pFab and triclosan system has the potential to be alluring for the synthesis of recombinant proteins. Moreover, the production of biopharmaceuticals, gene therapy products, and other uses requiring the absence of antibiotic resistance sequences or residues may be possible using pFab and its variants. In this experiment, the plates were checked and inoculums for ligations of FC33, PSDC115, DS9456 and DS9457 were made Protocol for mini preparation showed the band for the plasmid, and the PUC19 gel image shows ligation and PUC19 alongside with DNA ladder. The DNA molecules may be quickly and efficiently isolated, recognised, and purified using agarose gel electrophoresis. Using fluorescent dyes, which can identify up to 20 pg of double-stranded DNA by looking at the gel under UV light, the position of DNA can also be detected. Compared to polyacrylamide gels, agarose gels have a lesser resolution power but a more comprehensive range of separation. It is simple and effective to separate, recognise, and purify the DNA molecules using agarose gel electrophoresis. The position of DNA can also be determined using fluorescent probes to stain the gel, which can detect up to 20 pg of the double DNA by scrutinising the gel in UV light. Agarose gels give a more complete range of separation but a substantially inferior resolution power than polyacrylamide gel electrophoresis (Pandey et al., 2020).
In gel, lane 1 which showed DNA ladder, that is the well defined fragment in the gel. Lane 4 which is smaller in size than lane 4 and contains PSDC115 and PUC19 fragment are moving faster in the gel then the fragment present in lane 2. Monomers of PSDC115 behaved essentially the same way as monomers of FC33 and DS956, except that PUC19 DNA and DS941 generally formed higher levels of Diemers. Monomeric did form PSDC115 visible levels of dimers in FC33 and DS956 strains (Bradburne, 2014). . The intersubunit functionality can, in the simplest case of homodimers, offer extra, shared binding affinity for noncompetitive ligands, mediate conformational as vehicles for regulatory reactions among the two nonoverlapping active sites, and stabilise the dimer in comparison to the monomer . Many enzymes from hyperthermophilic species are higher-order oligomers than their mesophilic equivalents, providing evidence in favour of the stabilizing theory (Thoma et al., 2000).
Shorter DNA fragments passed through the gel matrix’s pores more quickly than longer ones as it runs. The longest fragments of DNA remained close to the wells after the gel has been running for a while, whereas the shortest pieces will be near the positive end of the gel. Each band was made up of several identically sized DNA fragments that have migrated together in groups to the same location. An isolated DNA fragment (or even a modest collection of DNA fragments) wouldn’t showed up on a gel by itself (Rifai, 2017).
In our results there are two types of fragemts was observed mononers and dimers. These findings are consistent with the same investigation that was conducted utilizing Cyclophilin A that is a cytosolic receptor for the immunosuppressive medication cyclosporin A, that has activity as a PPIase. In E. coli M15, the recombinant human CyPA gene has been expressed. Salting-out, Sephacryl S-100, and DEAE-Sepharose CL-6B column chromatography were all used for purification. The spectrometry and SDS-PAGE both revealed the molecular weight to be around 18 kDa. Native-PAGE and western blotting results revealed three bands, which were confirmed by the gel filtration results (Zhang et al., 2020).
Recombinant DNA technology was just a theory in the previous century, suggesting that by controlling the gene expression of targets, desired qualities may be enhanced in living things. However, this sector has recently been shown to have unique effects in improving human existence. Vital proteins can now be produced safely, affordably, and sufficiently to meet dietary and medical demands. This method can address essential aspects of life like increasing food and resources, improving health, and resisting many detrimental environmental consequences. It has transdisciplinary applications (Ling & Shibata, 2002). Genetically engineered plants, specifically in agriculture, have enhanced resistance to dangerous agents, greater adaptability for higher success, and better production yield. Recombinant medications are also now assured of usage and are swiftly acquiring commercial clearance. Techniques for genetic alteration, gene therapy, and bioremediation are also often used to treat life-threatening disorders. Because of its tremendous development and wide range of applications, this review article primarily focuses on the significance of recombinant DNA technology and its future applications in everyday life (Khan et al., 2016).

inguage, Meaning, and Concepts
no one says “Io»ñ” when a stranger sneezes in the grocery store. In meeting someone for the first time, but holding packages in your right hand, have you instead extended your left in greeting* In Saudi Arabia, this action would be
construed as highly disrespectful. Have you ever taken public transpormtion during rush hour? Do the passengers waiting to board generally rriose aside to let people off the train first? In Moscow, nobod}• steps aside; in Japan, people matt so long that they pre.ctically miss the train! In England, pants are called “trousers,” women’s underwear “pants,” suspenders “braces,” and garter belts
“suspenders.” You can imagine the confusion that would ensue if an American businessman told his English client he needed to find a shop where he could bu)’ new pants and suspenders because his luggage had been lost. The English- man would either assume the American was a cross-dresser or send him to a lingerie shop to buy something special for his wife. Even your sociology class ’ probably has a different culture—language, meanings, symbols—from a biol- ogy or dance class.
Another way to thjnk about culture is that it is a may of organizing our experience. Take our symbols, foc example. What does n red light mean? It could mean that an alarm is sounding. tt could mean that sociething is X-rated (the “red-light” district in Amsterdam, for instance). It could mean “stop.” There is nothing inherent about the meaning of the red hght. It is embedded within our larger culture and therefore is part of a web of meanings. You can- not change one without affecting the others.
Culture even includes our language. According to the Sapir-Whorf thesis in linguistics, the language we speak direcdy influences (and reflects) the way we think about and experience the world. On a more concrete level, if you speak another language, you understand how certain meanings can become lost in uanslation—you can’i always say ezacdy what you want.

Ideology
Nonmaterial culture, in its most abstract guise, takes the form of ideology. Ideology is a system of concepts and relationships, an understanding of cause and effect. For example, generally on airplanes you’re not allowed to use the
. toilets in the first-class cabin if you have a coach-class ticket. Why no t? tt’s not as if the lavatories in first class are thar much better. What’s the big deal? We subscribe to an ideology that the purchase of an airline ticket at the coach, business, or first-class fare brings with it certain service expectations-that an expensive £irst-class ticket entitles a passenger to priority access to the lava- tory, more leg room, and greater amenities, such as warm face towels. The ideology is embedded within an entire sedes of suppositions, and if you cast aside some of them, they will no longer hold together as a whole. IN everyone flying coach started to hang out in first class, chatting with the flight atten- dants and using the first-class toilets, the system of class strati£cation (in air planes at least) would break down. People would not be willing to pay extra for a iirst-class ticket; more airlines might go bankrupt, and the industry itself would erode.
Even science and religion, which may seem like polar opposites, are both ideological frameworks. People once believed that the sun circled acound the earth, and then, in the late fifteenth and early sixteenth centuries, along came Copernicus, Kepler, and Galileo, and this system of beliefs was turned inside

out. The earth no longer lay at the center of the universe but orbited the sun. This undeistanding represented a major shift in ideology, and it was not an easy one to make. In a geocentric universe, humans living on earth stand at its center, and this idea corresponds to Christian notions that humans are the lords of the eatth and the chosen children of God. However, when we view the eaith as a rock orbiting the sun, just like seven other plancts and countless subpłanetary bodies, we may feel sigriificantly less special and have to adjust our notion of humanity’s special role in the uińvetse. People invest a lot in their belief systemu, and those wiio go against the status quo and qucstion the prevailing ideology may be severely puriished, as was Galileo.
More receritly, the 2000 presidential clecdon had the potential to shatter the ideology of democracy—that is, the behcf that the candidate who zeceives the most votes ascends to power. The winner of the popular vote, Al Gors was in fact defeated by George W Bush, wŁo accumulated the requisite num- ber of Electoral College votes after the Supreme Court interceded on the mat- : ter of voter irregulaóties in Florida, the tie-breaker state. The concept of the: Electoral College ęoon becarrie a hot topic od debate, but the final electioit iesult did not prompt riots in die streec. As it turned out, the eritire ideology of Amencan democracy did not crurnble.
Of course, on occasion ideologies do shatter. The fall of the former Sovi Union, for example, marlred not just s tnnsition in government but the sha tering of a particular brand of Commurfist ideology. Similaily, when aparthei was abolished in South Afiica, more than just a few laws changed; a total reo ganization of ideas, beliefs, and social telations followed. Often, ideologi change comes more slowly. The fight ton women’s rights, including equal pa ” oogolng even todar but womcn won the right to vote way bac/c in 1920.

e culture, subculture as a concept can be a moving target: It’s hard ro lock i one specific deTuition of the term. Historically, s ubcultures have been ned as groups united by sets of concepts, values, symbols, and shared eaning specific to the members of that 6’oup. Accordingly, they frequentl} e seen as vulgar or deviant and are often marginalized. Part of the original ipetus behind subculture studies was to gain a deeper understanding of indi- duals and groups who traditionally have been dismissed as weirdos at best nd deviants at worst.
For example, man} music genres have affiliated subcultures: hip-hop, hard core, punk, Christian rock. High-school cliques may verge on subcultures—the jocks, the band kids, the geeks—although these groups don’t really go against the dominant society, because ath1eticisrr+, musical talent, and intelligence are fairly conventional values. But what about the group of kids who dress in black
ear heavy eyeliner? Maybe teachers simply see them as moody teenagers with a penchant for dark fashion and extreme makeup just seeking to annoy the adults in their life, but perhaps their style of self-presentation means more to them.
Goth culture has its roots in the United Kingdom of the 1980s. It emerged as an offshoot of post-punk music. Typified by a distinctive style of dress— namely, black clothing with a Victorian flair—and a general affinity for gothic and death rock, goth culture has evolved over the last three decades, Cth many internal subdivisions. Some goths are more clrawn to magical or religious aspects of the subculture, whereas others focus mainly on the music. Even the term goth has different meanings to people within the subculture: Some see it as derogatory; some appropriate it for their own personal mearñng. An internal struggle has grown over who has the right to claim and define tHe label.

Among the most pervasive and visible forms of culture in modern societies are those produced by the mass media. We might define media as any formats or vehicles that carry, present, or communicate information. This definition would, of course, include newspapers, periodicals, magazines, books, pam- phlets, and posters. But it would also include wax tablets, sky writing, web pages, and the children’s game of telephone. We’li flisr discuss the history of the media and then tackle theory and empirical studies.
From the Town drier to the Facebook Wall: A Brief History
When we talk about the media, we’re generally talking about the mass media. The first form of mass media was the book. Before the invention of the print- ing press, the media did exist—the town crier brought news, and royal mes- sengezz uavHeb by horseback, every now and then hopping off to read a scroll—but they did not exacdy reach the masses. People passed along most information by word of mouth. After the 1440s, when Johannes Gutenbei developed movable type for the printing press, text could be printed mu more easily Books and periodicals were produced and circulated at m greater rates and began to reach mass audiences. Since that time the t media arid uoiJ medls have become virtually synonymous.

he innovations didn’t stop there, however. In the t 880s along came mother invention: the moving picture or silent film. Its quality was not the best
.r fitst, but it improved over time. In the 1920s sound was added to films. For many, this represented an irrrprovement over the radio, which had come along out the same time as the silent film. Television was invented in the i930s, though this technolog}’ didn’t make its way into most American homes Wti1 after U’oild War II. During the postwar period, new forms of media tech- nolog’ quickly hit the market, and the demand for media exploded: glossy magazines; color televisions; blockbuster movies; Betarriax videos, then VHS videos, then DVDsi vinyl records, then eight-track tapes, then cassette tapes, then CDs—and once the Internet came along, the sky was the limit! In 2013, 70 percent of the American population had broadband at home, with access flustered among the younger, wealthier, and better educated (Zickuhr &
Smith, 2013).
You’re well aw’are of all the forms the media come in, but let’s stop for a minute and contemplate the impact certain forms, such as television, have had on society. Again, televisions didn’t become household items in the United States until after World War II. From 1950, the year President Harry S. Truman ftrst sent military advisors to South Viemarri, to t 964, when Congress approved the Gulf of Tonkin Resolution calling for isctory by any means nec essary, the share of American households with television sets increased from

Likewise, television played a large role in the civil rights movement of the 1950s and 1960s.

Hegemony: The Mother of All Media Terms
£feqemony a condi iron by which a dominant group uses its power to elicit the volunitary ‘consent’ of ttie masses
I l
All of us might be willing to agree that, on some level, the media both reflect culture and wr›rk to produce the ver} culture they represent. How does tlus dynamic work? Antonio Gramsci, an Italian political theorist and activist, came up Cth the concept of hegemony to describe just that. Gramsci, a Marxist, was imprisoned by the Fascists in the 1920s and 1 930s; while in jail, he attempted to explain u hy the working-class revolution Marx had predicted never came to pass. He published his findings in his “prison notebooks” of 1929—55 (Gramsci, 1971). In this vein, then, hegemony “refers to a historical process in which a dominant group exercises ‘moral and intellectual leadership’ through- out socie9• by winning the voluntary ‘consent’ of popular masses” (Kim, 200t). This concept of hegemony stands in contrast to another of Gramsci’s ideas, domination. If domination means getting people to do what you want through the use of force, hegemony means getting them to go along with the sta- tus quo because it seems like the best course or the natural order of things, Although dorriinadon generally involves an action by the state (such as the fascist leaders who imprisoned those who disagreed with them), “hegemony takes place in the rea1tn of private institutions . . . such as families, churchs trade unions, and the media” (Kim, 2001). For example, if free-market capiJ- ism is the hegemonic economic ideology of a given socie 9, then the state d
not have to explicidy work to inculcate that set of principles into its citize Rather, private institutions, such as families, do most of the heavy lifting in regard. Ever wonder why children receive an allowance for taking out the m and doing other household chores? Gramsci might argue that djs is the . capitalist free-market ideology is insulled in the individual within the pti realm of the family.
The concept of hegemony is important for understanding the impact the media. It also raises questions about the tension between struck agency. Are people molded by the culture in which they live, or do they 8C participate in shaping the world around them? As we discussed earli6t chapter, it’s not an either/or question. Below v e’ll talk about some of* debates between structure and agency with regard to the media, look at S examples of hegemony in practice, and discuss the possibilities for coUtlt tural resistance.

These quesńons are all examples of textual analysis, analysis of the content of media its various forms, one of the important strands of study to materialize in the
ke of Gramsci’s work.
DurÍng the 1960s and 1970s, academic z nsãies focused almost solely on texts—television talk shows, newspapers, magazine pages. Finally, scholars reef ognizeö the importance of finding out how people read and interpret, and are affected by bese texts: Audience studies wete born. The held of psychology has expended a lot of time investigating clsims about the effects of televi- sion on children, and the debate continues. Sociologists have explored the way women read romance novels or how teenage girls interpret images of super- thin models in magazines. For example, in Reedïżg /ée Romatice: Women, P‹itriarcłzf,
«d fØ»ñr U/ermo (1987), Janice Radway argues that women exhibit a great deaÎ of individual agency when reading romance novels, which helps them cope with their daily hves in a patriarchal society by providing both escapes fr rri the drudgery of everyday life and alternative scripts to their readers. We are not just passive receptors of media; as readers or viewers, we es9erìence texts through the lens of our own critical, interpteove, and analytical processes.

Finally, section D of die illustration represents the long-term, unintended effects of the media. many people, not just cultural conservatives, argue that we have been desensitized to violence, sexuai imager j, and oder content that some people consider inappropriate for mass audiences. In the film industry; for example, the Production Code, also known as the Harm Code, was a set of standards created in 1930 (although it wasn’r officiallj enforced until 1934) to protect the moral fabric of society. The guidelines were fairly strict, and they were a testament to the mainstream ideologies of the time (see the box on pages 96-97). Slow.ly, however, the power of the code began to erode because of the ›minence of telemsion, foreign films, arid the fact that being condemned as immoral didn’t prevent a Um from becorriing a success. In ] 9G7 thy 5c›d2 was abandoned for the movie rating system. Over time, we have grown accus- tomed to seeing sexually explicit material In films, on television, and on the Internet. Those who lament this desensi6zation seek to reinstimte controls over media content.

Racism in the Media
On December 22, 1941, two weeks efter the ]apanese attack on Pearl Harbor, Time magazine ran an article titled “How to Tell Your Friends from the Japs.” There were annotated photographs to help readers idenñfy characteristics thai would distinguish, for instance, friendly Chinese from the ]apanese, American enemies during World War II. The magazine offered the following rules or iliumb, although it admitted that they mere “not always reliable”:
- Some Chinese are tall (average: S 5 in.), Virtually all ]apanese are short (a erage: 5 ft. 2-’Zz in.).
- japanese are likely to be stockier and broadet-hipped than short Chines

Women’s magazines have been heavily crit- although some researchers (such as Angela McRobbie from the United pm) have taken care to show that women who are active, critical readers ijoy reading women’s magazines. However, as the Canadian sociologist Currie points out 1999), although girls can choose which magazines, if read and iIOw rO Critically read them, they can’t control the images avail- them in those and other texts.
other focus of feminist media critiques has been images of violence nst women. jean IObourne has become one of the most popular lecturers ollege arid university campuses across America. In 1979 she released a film ed U/log Ui lofty: Ndrrm/i»g i Image o/ Pomsn, in which she examines the
/s in which women are maimed, sliced, raped, and otheruñse deformed in vertising images. One classic example is a photo that shows the image of a
.man’s body in a garbage can, with only her legs and a fantastic pair of high els on her feet visible. The message is clear: These shoes are, literally, to die
- Kilbourne’s point is clear, too: Such images help sustain a kind of symbolic olence against women. In this critique, advertising does not just reflect the derlying culture that produced it but also creates desires and narratives that
enter women’s (and mens) hves with causal force.
Of course, there’s always room for innovation. Some girls (with the help of their parents) have responded by creating their owri magazines that focus on topics other than makeup, clothing, and boys, as mainstream teenage maga- zines do. for example, New doo» G/r/i is written and edited by girls aged 8 to 13 and contains no advertisements. Likewise, magazines exist for adult women that have more pro-woman messages; Mr. magazine was founded in 1971 dur-
Because such magazines don’t accept advertising from huge makeup compa- nies and designer fashion houses, however, they are often less economically viable rhan mainstream worr+en s magaxines, which carry ads on as many as 50 percent of their pages. Brick magazine (“Its a noun; it‘s a ver t’s a maga- zine’3, which has been around since t 996, is a self-declared feminist response to pop culture. It is supported by advertisers but is a not-for-profit publication.
Some advertisers have responded to feminist critiques of the media Cth new approaches. In 2005 Dove. a manufacmrer of skin-care products, launched a new seties of ads backed by a social awareness program called rhe Campaign for Real Beauty. Instead of models, the ads featured “real” women complete with freckles, frizz}• hair, wrinkles, and cellulite. The images were intentionally meant to offer a contrast to the images we’re accustomed to seeing. And, as Dover advertisers have said, “firming the thighs of a size 2 supermodel is no challenge” (Triester, 2005). The latest version of Dove’s Real Beauty campaign shows side by-side sketches of tire same woman as drawn by a sketch artist. The first image is drawn based on the woman’s description of herself and

Receiving Apples approval is important use once developers have made an app for Apples iOS platform, they ot sell it .nywhere but the iTunes store. Is Apple protecting its shoppers ir+g the app developers through a combination of monopoly power and owy threats? As corporate control of the media becomes more and more ized (owned by fewer and fewer groups), the concern is that the range opinions available will decrease and that corporate censorship (the act of
9pressing information that may reflect negatively on certain companies and/or ir affiliates) will further compromise the already-tarnished integrity of the
tream media.

One of the MIT projects—VGAZA or Virtual Gaza—allowed Palestinians in the Gaza Strip to document crises and share local stories glohally while under embargo. But not even the Internet is beyond the realm of pohtical economy. Srrialler sites, for example, cannot afford ro have sponsored links on Google’s search pages.
Consumer Culture
America is often described as a consumer culture, and rightly so. In my inter- her’ with sociologist Allison rugh, she pointed out that “corporate marketing to cluldren is a 22 billion dollar industry.” She then added, “Children 8 to 11 ask for beoveen W’o and four toys [for Christmas], and they receive eleven on aver- age!” (Conley, 2011a). Sales on mxjor patriotic holidays (Veterans Day, Memo- rial Day, Presidents’ Day) thrive as a tesult of the notion that it is our duty as American citizens to be good shoppers. As Sharon Zukin points out in her book on shopping culture, Point of Pyrcñai•.- How’ Xboppi’ng Changed American Cul- ture (2003), 24 hours after the terrorist attacks of September 11, 2001, h4ayot Rudy Giuliani urged New Yorkers to take the day off and go shopping. It’s the tie that binds our society; everyones got to shop. iialls are our modern day marketplaces—they are where teenagers hang out, where elderly suburbanites get their exercise, and where Europeans come as tourists to see what Ameri- can culture is all about. The term ru»rrrrfm, however, refers to more than

just buying merchandise; it refers to the belief thxt happiness and fulfilment can be achieved through the acquisidon of matenA possessions. Versace, j. Crew, and realtors in certain hip neighborhoods are not just peddling shoes, jeans, and apart- ments. They are also selling a self-image,
a lifestyle, and a sense of belonging and i*? self-wonh. The media, and advertising in particular, play a large role in the creation
and maintenance of consumerism.
Advertising and Children
The rise of the consumer-citizen has met with increasing criticism, but how doe our society produce these consumer
citizens* The Canadian author and activi ‘
Naomi Klein published No Logo.- TaN»g km at the Brand Bellies N 2000; in thi book Klein analyzes the growth of advertising in schools. Pepsi and Co Cola now bargain for exclusive rights to sell their products witkin schools, brand-name fast foods are often sold in cafeterias The logos of compani that sponsor athletic fields are displayed prominendy. This has been commo place in many colleges and universities for some time now, but the increas’ presence of advertising in middle and high schools should also be noted. .
One striking example is Channel One, which has been airing in sch around the United States since 1990 (Rhode Island was the only state to re Channel One funding). In exchange for television sets, video equipment, satellite dishes, schools are required to show 12 minutes of prepackaged -‘ granuning every day. Although Channel One provides news and public af informañon, its programming also includes to minutes of commerciâi 12-minute segment. One analysis found that only 20 percent of air devoted to “recent political, economic, social, and cultural stories”; the r ing 80 percent of the prepackaged programming includes sports, weath other topics, as well as advertisements for Channel One itself. Studie found that Channel One cosr taxpayers JI.8 billion a year in lost schoo;t
of that amount, $300 million was lost to commercials alone (Molnar & S 1998). Meanwhile, Channel One charges advertisers almost $200,000 I 30-second segment. Channel One is disproportionately found in lowei-
schod disnicts that struggle with funding for books and technologji rti
disadvantaged students in these schools are exposed to more adver ’ and fewer academic lessons than their peers in systems that can afford this kind of sponsorship. ‘

Until about 1960, the proportion of unique names for white Americans hovered around 20 percent for girls. For blacks ir had always been higher— around 30 percent. During the 1960s, the number of white girls with unique names started to inch up to about 25 percent, but for blacks, it literally sky- docketed, peaking around i 9T at more than 50 percent for girls and reaching almost 40 percent for boys in 1975 (hased on Illinois data).
