13. As you recall, a process called catabolite repression prevents high level of transcription of lacZYA genes when glucose is present in the growth medium. Low levels of glucose lead to production of CAMP, which enables CRP to bind to the lacZYA promoter. If the gene encoding CRP were to experience a loss-of-function mutation, what would be the expected outcome? a. Reduced level of lacZYA transcription in a medium containing only lactose (no glucose) b. No change in lacZYA transcription in a medium containing only lactose (no glucose) c. Increased level of lacZYA transcription in a medium containing only lactose (no glucose) e. Increased level of lacZYA transcription in a medium containing both lactose and glucose

IIVY is a LysR regulator, and it helps control transcription of a neighboring gene, ilvC. IlvY can either bend the DNA and block RNAP's access to ilvC's -35 promoter site, or it can allow access to the ilvC -35 site, thereby promoting ilvC transcription. What determines whether llvY is repressing or activating transcription from the ilvC promoter? The presence of the co-inducer acetolactate - acetolactate binds to llvY and changes llvY's shape such that it doesn't block the -35 of the ilvC promoter. IlvY represses ilvC transcription when the IlvC protein is bound to llvY, and it activates ilvC transcription when the lvC protein is not present to bind to llvY. The presence of the co-inducer valine - when valine is present, it binds llvY and causes llvY to repress transcription from the ilvC promoter. The presence of the co-inducer acetolactate - acetolactate induces negative supercoiling at the ilvC promoter, which represses ilvC transcription.
