(C) In the $lac$ operon,the structural genes are $z$,$y$,and $a$.- The $z$-gene codes for $\beta$-galactosidase,which is responsible for the hydrolysis of lactose into galactose and glucose.- The $y$-gene codes for permease,which increases the permeability of the cell to $\beta$-galactosides.- The $a$-gene codes for transacetylase.- Therefore,the statement that the $y$-gene codes for transacetylase is incorrect,as it actually codes for permease.
