Vedclass · Answer

(D) In the $lac$ operon,$lactose$ acts as the inducer. When $lactose$ is present in the medium,it enters the cell and is converted into $allolactose$ by a small amount of $\beta-galactosidase$ enzyme. $Allolactose$ binds to the repressor protein,preventing it from binding to the operator region,thereby allowing transcription to proceed. $Glucose$ and $galactose$ do not act as inducers for the $lac$ operon. Therefore,both $A$ and $B$ do not act as inducers.

Which of the following does not act as an inducer in the $lac$ operon?
