Vedclass · Answer

(C) In the $lac$ operon,the inducer is $allolactose$,which is an isomer of lactose. For an inducer to function in the $lac$ operon,it must be able to bind to the repressor protein,thereby preventing the repressor from binding to the operator region. Glucose and galactose are monosaccharides that do not possess the structural configuration required to bind to the $lac$ repressor protein. Therefore,they cannot induce the expression of the $lac$ operon genes.
