Vedclass · Answer

(D) In the $lac$ operon,the presence of lactose acts as an inducer.When lactose enters the cell,a small amount of it is converted into its isomer,$allolactose$,by the enzyme $\beta-galactosidase$.$Allolactose$ binds to the repressor protein,causing a conformational change that prevents the repressor from binding to the operator region.This allows $RNA$ polymerase to transcribe the structural genes $(lacZ, lacY, lacA)$,thereby inducing the operon.

Which of the following acts as an inducer for the $lac$ operon?
