Show transcribed image text Lactose metabolic activity in the lac operon is represented in the image below. For the lac genotypes listed below, the repressor mutant I^- cannot bind to the operator, the I^S mutant always binds to the operator, and the O^C mutation prevents the repressor from binding the operator. The F' plasmid delivers the wild-type, O^+, and I^+ gene into the mutant strains. Determine the nature of the expression of the lac genes, L, and label each genotype as constitutive, inducible, or repressed. Assume that all promoters are wild type.
