Determine the expression of lac genes in mutants, the genotypes of which are shown below. Each of these bacterial cell types is grown in the absence of glucose and evaluated to determine whether they produce -galactosidase and/or lactose permease when lactose is absent or present. Complete the table below by filling in the expected phenotype (inducible I, constitutive C , or uninducible U) for each enzyme in each strain. The wild-type strain's description is already provided as an example. (1 pt each) .
