Lactose would not be converted into the inducer and the operon could not be induced.

Vedclass · Answer

(C) In the $lac$ operon,a basal or low level of $Lac Z$ expression is essential even in the absence of lactose. This low level of $\beta$-galactosidase enzyme is required to convert lactose into allolactose,which acts as the inducer. If the gene expression were completely repressed,lactose could not be converted into the inducer,and therefore,the operon could never be induced even in the presence of lactose.

What effect would you expect if gene expression of the $lac$ operon were completely repressed?
