$b$-galactosidase,permease and transacetylase.

Vedclass · Answer

(B) The lactose operon (model proposed by Jacob and Monod) produces three structural enzymes: $b$-galactosidase $(z)$,permease $(y)$,and transacetylase $(a)$.$b$-galactosidase $(z)$ is responsible for the hydrolysis of lactose into glucose and galactose.Permease $(y)$ is required for the transport of lactose into the cell.Transacetylase $(a)$ transfers an acetyl group from acetyl-$CoA$ to $b$-galactosides.

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

Select the correct option for $\beta$-galactosidase.

$A$: Operator gene is functional when it is not blocked by repressor.
$R$: Regulator gene produces active protein only which acts on operon system in $E. coli$.

In the $lac$ operon,the structural genes are switched off when:
