Vedclass · Answer

(C) The $lac$ operon in $E. coli$ consists of three structural genes: $lacZ$,$lacY$,and $lacA$.These genes are arranged in the order $z, y, a$.$lacZ$ codes for $\beta$-galactosidase,which hydrolyzes lactose into glucose and galactose.$lacY$ codes for permease,which increases the permeability of the cell to $\beta$-galactosides.$lacA$ codes for transacetylase,which transfers an acetyl group from acetyl-$CoA$ to $\beta$-galactosides.Therefore,the correct sequence is $z, y, a$.

What is the correct sequence of structural genes in the $lac$ operon?
