Step 1
It does so by binding to a specific DNA sequence called the CRP binding site, which is located upstream of the lac operon promoter. Show more…

The cAMP response protein (i.e. CRP or CAP) activates the transcription of the lac operon involves each of the following EXCEPT: - Cooperative DNA binding - Recruitment of RNAP - Allosteric changes of CRP - Structural changes of DNA - Steric hindrance
Adi S.
Which of the following would allow transcription from the Lac operon a. A mutation on the CAP protein that mimics the cAMP-bound form b. A mutation on the CAP protein that prevents cAMP binding c. Disruption of the -10 and -35 promoter elements of the lac promoter d. A mutation that prevents CAP binding to DNA. e. High glucose concentration A mutation that changes CGC to CTC is best described as a. Nonsense mutation b. Frameshift mutation c. Transition d. Silent mutation e. Transversion
For the $E$. coli lac operon, when lactose is present: a. and glucose is absent, cAMP binds and activates catabolic activator protein (CAP). b. and glucose is absent, the level of cAMP decreases. c. activated CAP binds the repressor protein to remove it from the operator gene. d. the cell prefers lactose over glucose. e. RNA polymerase cannot bind to the promoter.
