Which of the following acts as an inducer in the lac operon? Correct Answer lactose
When lactose is present in the medium, it binds to the repressor protein changing its conformation while preventing the former’s binding at the operator region. Thus the structural genes are transcribed and lactose is catabolized, therefore lactose acts as an inducer in the lac operon.
