Lactose

Vedclass · Answer

(A) In the $lac$ operon,the regulator gene produces a repressor protein that binds to the operator region,preventing transcription. When lactose is present in the medium,it acts as an inducer. Lactose binds to the repressor protein,causing a conformational change that prevents the repressor from binding to the operator. This allows $RNA$ polymerase to transcribe the structural genes,thereby initiating the expression of the $lac$ operon.
