Inducers which bind with repressor protein

Vedclass · Answer

(C) In the $lac$ operon model,the repressor protein is synthesized by the $i$-gene. In the absence of the inducer (lactose),the repressor protein binds to the operator gene,preventing $RNA$ polymerase from transcribing the structural genes. When lactose is present,it acts as an inducer. Lactose binds to the repressor protein,causing a conformational change that prevents the repressor from binding to the operator gene. This allows $RNA$ polymerase to transcribe the structural genes,thus enabling the expression of the operon.

In the $lac$ operon model,lactose molecules function as:
