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 region and prevents $RNA$ polymerase from transcribing the operon. 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. This allows $RNA$ polymerase to access the promoter and transcribe the structural genes. Therefore,lactose functions as an inducer that binds with the repressor protein.

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