Question: for e coli strains below use y or n to...

Question details

Problem 1. For E. coli strains below, use (Y) or (N) to indicate whether a functional protein is being produced by b-galactosidase and permease genes for each of the environmental conditions. Assume that the second copy of lac operon (where indicated) is carried on an F factor. (1pt/genotype) Regulatory gene lac operon E. coli chromosome Encodes lactose lace Encodes B-galactosidase galactoside terminator i promoter CAP site Operator site (aco) permease ansacetylase lac promoter (acP) Lactose absent Lactose present Strain genotype at lac LB galactosidase permease B-galactosidase permease
