In prokaryotes, such as E. coli, the activity of the regulatory CAP is an example of Group of answer choices negative regulation because CAP binding activates the repressor positive gene regulation because the lac operon is expressed at a high rate whenever lactose is present positive gene regulation because activation of CAP enhances expression of the operon both positive and negative gene regulation because cAMP acts both as a corepressor and as an activator of CAP negative gene regulation because cAMP turns off CAP
