In an experiment, E. Coli that are auxotrophic for methionine, tryptophan, and adenine biosynthesis are grown on petri dishes containing rich media with all of these nutrients. The bacteria grow into normal colonies. The same bacteria are plated onto media that is lacking those 3 nutrients (minimal media) and no growth is observed. A second strain of E. Coli which is auxotrophic for histodine, and leucine is also able to grow on rich media but not minimal media. After mixing...

The ima operon of E. coli controls "imaginary" biosynthesis (for this problem "imaginary" is a small vitamin that E.coli must biosynthesize or obtain from their environment in order to survive) . In addition to three structural genes (A, B, and C), there is also a regulatory region which we will call R for regulatory that is located at +15. Assays have been developed to independently monitor the activity of the protein products encoded by these genes. R- is a mutant regulatory...
