Transcription of the genes in an inducible operon

Question

Quizplus · Accepted Answer

In an inducible operon, the transcription of the genes is initiated when the substrate of the metabolic pathway is present. The substrate acts as an inducer and binds to the repressor protein, releasing it from the operator site and allowing RNA polymerase to transcribe the genes. The transcription of the genes stops when the substrate is no longer present, and the repressor protein binds to the operator site, preventing RNA polymerase from transcribing the genes.
