Describe the phenotypes of the following E. coli mutants when grown in two different media: glucose only and lactose only. Explain why. (6 points) a. A strain with a mutation in the gene encoding the lacI gene; the mutant LacI protein cannot bind allolactose. b. A strain with a mutation in the gene encoding CRP; the mutant form of CRP binds but cannot release cAMP. c. A strain in which the Shine-Dalgarno sequence has been deleted from the gene encoding adenyl cyclase.
