Gene Regulаtiоn (24 pts) In E cоli, the regulаtiоn of lаcZYA (the lac operon) expression and subsequent production of functional proteins can be disrupted by mutations in the genome of E. coli genome. This demonstrates the central role of an organism's DNA sequence for giving an organism its particular physiological properties. This question asks you to think about how amounts of the protein beta-galactosidase produced (– = none; + = a small amount, ++ = a moderate amount, +++ = maximal amount) by E. coli depends on the environment (what nutrients are in the growth media) and on the genetics (mutations in the relevant DNA). For each of the strains (varieties) of E. coli listed below (a, b, c, d, e, and f), select the pattern of functional beta-galactosidase production (1, 2, 3, 4 or 5) that you would expect to see the under the different media conditions shown (Gl, gl, GL, and gL). Note: Not all patterns may be seen. The same pattern may be seen for more than one strain of E. coli. Strain a --> Pattern [a] Strain b --> Pattern [b] Strain c --> Pattern [c] Strain d --> Pattern [d] Strain e --> Pattern [e] Strain f --> Pattern [f]
