Vedclass · Answer

(B) In the $lac$ operon system,the enzyme $\beta$-galactosidase is encoded by the $lacZ$ gene. This gene is part of an inducible operon system. In the absence of lactose (the inducer),the repressor protein binds to the operator region,preventing $RNA$ polymerase from transcribing the structural genes ($lacZ$,$lacY$,and $lacA$). Therefore,$\beta$-galactosidase is not produced when lactose is absent.
