What is the name of the molecule that binds to CAP to activate transcription of the lac operon? A)galactose B)ATP C)cAMP D)lactose E)glucose

Question

Quizplus · Accepted Answer

The molecule that binds to CAP (catabolite activator protein) to activate transcription of the lac operon is cyclic AMP (cAMP). When glucose is scarce and lactose is present, cAMP binds to CAP and the CAP-cAMP complex binds to the promoter region of the lac operon, increasing the affinity of RNA polymerase and facilitating transcription.
