Vedclass · Answer

(C) The $lac$ operon in $E. coli$ consists of three structural genes: $lacZ$,$lacY$,and $lacA$.$1$. The $lacZ$ gene codes for $\beta$-galactosidase,which is responsible for the hydrolysis of lactose into galactose and glucose.$2$. The $lacY$ gene codes for $\beta$-galactoside permease,which increases the permeability of the cell to $\beta$-galactosides like lactose.$3$. The $lacA$ gene codes for transacetylase,which transfers an acetyl group from acetyl-CoA to $\beta$-galactosides.Therefore,the correct set of enzymes is $\beta$-galactosidase,$\beta$-galactoside permease,and transacetylase.

Which one of the following sets contains enzymes coded by the structural genes of the $lac$ operon of $E. coli$?
