Show transcribed image text In E. coli, three closely linked loci have been identified. The loci are symbolized by d, m and s. Wild type alleles are superscripted with a plus, while mutant alleles are superscripted with a minus. When an inducer is present or absent, the level of Enzyme A is measured and the results for several different strains are given below. From the information given, determine which of the genes is the structural gene for Enzyme A, which is the regulator and which is the operator. There are no super-repressor mutants and assume all promoters are wild type!
