Vedclass · Answer

(C) In the $Lac$ operon:$1$. The $i$ gene codes for the repressor protein,which regulates the operon.$2$. The $z$ gene codes for $\beta-	ext{galactosidase}$,which hydrolyzes lactose into glucose and galactose.$3$. The $y$ gene codes for permease,which increases the permeability of the cell to $\beta-	ext{galactosides}$.$4$. The $a$ gene codes for transacetylase,which transfers an acetyl group to $\beta-	ext{galactosides}$.Matching these:$(a) - (iii)$$(b) - (i)$$(c) - (iv)$$(d) - (ii)$Therefore,the correct sequence is $(iii), (i), (iv), (ii)$.

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

Match the following genes of the $Lac$ operon with their respective products.
$(a)\; i$ gene $(i)\; \beta-\text{galactosidase}$
$(b)\; z$ gene $(ii)\; \text{Permease}$
$(c)\; a$ gene $(iii)\; \text{Repressor}$
$(d)\; y$ gene $(iv)\; \text{Transacetylase}$

Select the correct option.
