Problem
Scenario I: Explain what happens when E. coli bacterial cells in culture have abundant glucose available and no lactose.
Scenario II: Explain what happens when E. coli bacterial cells in culture are deprived of glucose, and the laboratory technician only provides lactose to the cell cultures.
Scenario III: Explain what happens when a point mutation involving a deletion of one base pair near the beginning of the gene coding for the activator protein occurs.
Scenario IV: Explain what happens when a point mutation involving an insertion of one base pair near the beginning of the region of DNA for the promoter occurs.
Scenario V: Explain what happens when a point mutation involving a substitution of one base pair for another occurs in the DNA region coding for one of the genes needed to metabolize lactose.
Scenario VI: Explain what happens when a point mutation involving one base pair substitution occurs in a noncoding region of the DNA near the lac operon.
