Question

Quizplus · Accepted Answer

The operator is the part of the operon that serves as a switch for the transcription of the gene. It can turn the gene on or off depending on whether a repressor protein is bound to it or not. The promotor is the site on the DNA where RNA polymerase binds to initiate transcription, and the repressor is a protein that can bind to the operator and prevent transcription from occurring. While all of these terms are important for regulating gene expression, only the operator fits the given definition.
