Now, for each region of the lac operon on the bacterial chromosome, I− P+ O+ Z+ Y−, determine whether the region is wild type (that is, it produces a functional protein or it's a correct protein binding sequence) or whether the region is mutated. A. The promoter sequence is correct/functional
B. The repressor protein is produced
C. The operator sequence is correct/functional Beta-galactosidase is produced from the lacZ gene.
D. Permease is produced from the lacY gene.
