Describe the positive control exerted by the catabolite activating protein (CAP). Include a description of catabolite repression
What will be an ideal response?
Regarding regulation of the lac operon, in the absence of glucose, CAP (dependent on cAMP and adenyl cyclase) binds to the CAP site and facilitates transcription (positive control). Transcription of the operon is inhibited in the presence of glucose (catabolite repression).
