Marketing Research and Data AnalysisWhich of the following statements about repressor proteins is TRUE? When a repressor protein is bound to its operator, it stops transcription by blocking RNA polymerase from binding to the promoter When a repressor protein is bound to its operator, RNA polymerase binds to the promoter and transcription then proceeds. When a repressor protein is present in a cell, transcription for the genes under the control of the repressor is stopped completely When a repressor protein binds to RNA polymerase, the polymerase molecule can no longer transcribe any genes in the cell Q5.4. What do operators and activator sites have in common? They are both proteins They are both part of the promoter. They both bind to activator proteins They are both DNA sequences Sub
