Vedclass · Answer

(A) In the $lac$ operon model,the structural genes and the regulator gene have specific functions:$1$. Gene $z$: Codes for the enzyme $\beta$-galactosidase,which is responsible for the hydrolysis of lactose into galactose and glucose.$2$. Gene $y$: Codes for the enzyme permease,which increases the permeability of the cell to $\beta$-galactosides.$3$. Gene $a$: Codes for the enzyme transacetylase.$4$. Gene $i$: Codes for the repressor protein,which binds to the operator region to prevent transcription in the absence of an inducer.Therefore,the correct matching is: $A-II, B-III, C-IV, D-I$.

List-$I$	List-$II$
