The bacterial cells were incubated in a medium containing both lactose and glucose. Describe the change, if any,
in the expression of the lac operon of such bacterial culture in the following conditions: (a). operator cannot bind with the repressor; (b). dysfunctional promoter that prevents its association with the RNA polymerase; (c). intracellular cAMP level is increased; (d). repressor cannot bind to the inducer.
(a) Theoperator is not bound to the repressor, RNA polymerase will bind at the promoter and the transcription occurs. When... View the full answer
