Question

Quizplus · Accepted Answer

The protein that regulates transcription by binding to the operator is known as the repressor. The operon is a unit of DNA that contains multiple genes and is controlled by a single regulatory region. The promoter is a region of DNA that initiates transcription. The operator is a regulatory region of the operon that controls access of RNA polymerase to the genes. CAP (catabolite activator protein) is a protein that activates transcription in response to glucose levels.
