When bound to the DNA,the repressor protein usually prevents attachment of the RNA polymerase to the __________.

Question

Quizplus · Accepted Answer

The RNA polymerase binds to the promoter region in order to transcribe genes in an operon. The operator region is the binding site for the repressor protein. So, when the repressor protein is bound to the operator region, it prevents RNA polymerase attachment to the promoter, thereby inhibiting transcription.
