Operator

Vedclass · Answer

(A) In the $Lac$ operon,the repressor protein is synthesized by the $i$ gene. When lactose is absent,the repressor protein binds to the operator site. This binding physically blocks the $RNA$ polymerase from transcribing the structural genes $(Lac\, z, Lac\, y, Lac\, a)$. Therefore,the operator is the specific site where the repressor binds to regulate gene expression.

At which site does the repressor bind in the $Lac$ operon?
