Repressor

Vedclass · Answer

(C) In the $Lac$ operon,the repressor protein is synthesized in an active form that binds to the operator region,preventing $RNA$ polymerase from transcribing the structural genes.When an inducer (lactose/allolactose) is present,it binds to the repressor protein.This binding causes a conformational change in the repressor,rendering it inactive.The inactive repressor can no longer bind to the operator,allowing $RNA$ polymerase to access the promoter and initiate transcription,thus switching the operon 'on'.

In the $Lac$ operon,to which component does the inducer bind to switch the system 'on'?
