Vedclass · Answer

(A) The $Lac-operon$ is a classic example of gene regulation in prokaryotes. In prokaryotes,gene expression is primarily regulated at the level of transcription initiation. The $Lac-operon$ consists of structural genes $(lacZ, lacY, lacA)$ whose expression is controlled by the binding of a repressor protein to the operator site,which prevents $RNA$ polymerase from transcribing the genes. Therefore,it is an example of regulation at the transcriptional level.

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