SOLVED: In a hypothetical bacterial operon, genes A, C, and D are expressed when substance "r" is present, but not when it is absent. Mutations in gene A cause protein 1 not to be produced, but only affect the production of protein 1. Gene B, which has been shown to be near the other genes, does not encode for a protein. Mutations in gene B cause genes A, C, and D to be expressed all the time regardless of the presence or absence of substance "r." Mutations in gene C cause protein 2 not to be pr

SOLVED:In a theoretical operon, genes A, B, C, and D represent the repressor gene, the promoter sequence, the operator gene, and the structural gene, but not necessarily in the order named. This operon is concerned with the metabolism of a theoretical molecule (tm). From the data provided in the accompanying table, first decide whether the operon is inducible or repressible. Then assign A, B C, and D to the four parts of the operon. Explain your rationale. (AE= active enzyme; IE= inactive enzym
