Multiple Choice
Multiple ChoiceWhen glucose is present:
A
cAMP is high, CRP binds to the activator binding site, and transcription of the lac operon is turned off.
B
cAMP is low, CRP binds to the site activator binding site, and transcription of the lac operon is turned on.
C
cAMP is high, CRP does not bind to the activator binding site, and transcription of the lac operon is turned on.
D
cAMP is low, CRP does not bind to the activator binding site, and transcription of the lac operon is turned off.
