Transcriptional level

Vedclass · Answer

(A) In prokaryotes like $E. coli$,the primary control of gene expression occurs at the level of transcription initiation.In the $lac$ operon,the regulation is primarily achieved by controlling the access of $RNA$ polymerase to the promoter site.This is mediated by the interaction of a repressor protein with the operator region,which prevents transcription when the inducer (lactose) is absent.Therefore,the correct level of regulation is the transcriptional level.

At which level is gene expression regulated in the $lac$ operon of $E. coli$?
