What role do cAMP and CAP play in transcription of lac operon genes? A) CAP binds the
Question:
A) CAP binds the CAP binding site of the lac promoter to carry out negative control of operon gene transcription, whereas cAMP blocks the CAP binding site and thereby allows fine-tuning of the system. |
B) CAP and cAMP form a complex that binds the CAP binding site of the lac promoter to carry out negative control of operon gene transcription. |
C) CAP binds the CAP binding site of the lac promoter to carry out positive control of operon gene transcription, whereas cAMP blocks the CAP binding site and thereby allows fine-tuning of the system. |
D) CAP and cAMP form a complex that binds the CAP binding site of the lac promoter to carry out positive control of operon gene transcription. |
