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 $z, y, a$.

$(a)\; i$ gene	$(i)\; \beta-\text{galactosidase}$
$(b)\; z$ gene	$(ii)\; \text{Permease}$
$(c)\; a$ gene	$(iii)\; \text{Repressor}$
$(d)\; y$ gene	$(iv)\; \text{Transacetylase}$

List-$I$	List-$II$
$a$. In lac operon $i$ gene codes for	$i$. Transacetylase
$b$. In lac operon $z$ gene codes for	$ii$. Permease
$c$. In lac operon $y$ gene codes for	$iii$. $\beta$-galactosidase
$d$. In lac operon $a$ gene codes for	$iv$. Repressor

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