Vedclass · Accepted Answer

The structural gene 'z' codes for $\beta$-galactosidase,'y' for transacetylase and 'a' for permease.

Vedclass · Answer

(D) In the $lac$ operon,the structural gene '$z$' codes for $\beta$-galactosidase,which is responsible for the hydrolysis of lactose into galactose and glucose. The structural gene '$y$' codes for permease,which increases the permeability of the cell to $\beta$-galactosides like lactose. The structural gene '$a$' codes for transacetylase. Therefore,the statement in option $D$ is incorrect because it incorrectly assigns the functions of genes '$y$' and '$a$'.

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

Identify the $INCORRECT$ statement from the following with reference to lac operon.

Lac-operon is an example of which one of the following types of regulation of gene expression?

Assertion $(A):$ Regulation of $lac$ operon by repressor is referred to as negative regulation.
Reason $(R):$ Repressor protein binds to the operator region and prevents $\text{RNA}$ polymerase from transcribing the operon.
