What would occur if the repressor of an inducible operon were mutated so it could not bind the operator?
A) irreversible binding of the repressor to the promoter
B) reduced transcription of the operon's genes
C) buildup of a substrate for the pathway controlled by the operon
D) continuous transcription of the operon's genes

Question

Quizplus · Accepted Answer

In an inducible operon, the repressor normally binds to the operator to block transcription. If the repressor cannot bind the operator due to a mutation, it cannot prevent RNA polymerase from transcribing the operon's genes, leading to continuous transcription.
