Regulatory gene

Vedclass · Answer

(A) The $Lac$ operon consists of three structural genes: $Lac-z$,$Lac-y$,and $Lac-a$.$Lac-z$ codes for $\beta$-galactosidase,$Lac-y$ codes for permease,and $Lac-a$ codes for transacetylase.The regulatory gene (often denoted as $i$-gene) is not a structural gene; it codes for the repressor protein that regulates the expression of the operon.Therefore,the regulatory gene is the correct answer.

Which of the following is not a structural gene of the $Lac$ operon?
