Vedclass · Answer

(A) The inducer for the $lac$ operon of $Escherichia \ coli$ is $lactose$ (specifically,$allolactose$,which is a metabolite of $lactose$).Normally,the $lac$ operon remains in an inactive state because the repressor protein binds to the operator gene,preventing transcription.When $lactose$ is present in the medium,it acts as an inducer.It binds to the repressor protein,causing a conformational change that prevents the repressor from binding to the operator gene.Consequently,the $RNA$ polymerase enzyme is free to bind to the promoter and transcribe the structural genes.
