Vedclass · Answer

(B) The $lac$ operon is a classic example of an inducible operon that is under negative control. In the absence of the inducer (lactose),the repressor protein binds to the operator region,which prevents $RNA$ polymerase from transcribing the structural genes. This binding of the repressor to the operator blocks the transcription process,which is defined as negative regulation. Therefore,the repressor acts as a negative regulator of the $lac$ operon.
