Vedclass · Answer

(D) In the $lac$ operon of $E. coli$, three structural genes are involved: $lacZ$, $lacY$, and $lacA$.$1$. $lacZ$ encodes $\beta$-galactosidase, which hydrolyzes lactose into glucose and galactose.$2$. $lacY$ encodes Permease, which increases the permeability of the cell membrane to $\beta$-galactosides like lactose, allowing it to enter the cell.$3$. $lacA$ encodes Transacetylase, which transfers an acetyl group from acetyl-CoA to $\beta$-galactosides.Therefore, the enzyme responsible for increasing the permeability of the bacterial cell to lactose is Permease.

List-$I$	List-$II$
$A$. Gene $a$	$I$. $\beta$-galactosidase
$B$. Gene $y$	$II$. Transacetylase
$C$. Gene $i$	$III$. Permease
$D$. Gene $z$	$IV$. Repressor protein
