How would a strain of Escherichia coli look under a microscope if it had a mutation that inactivated the protein MreB compared to a strain that had a functional MreB? Why does this happen? Would this effect cell division in the mutant strain? Explain. Which Fts protein has a similar cell division roll to MreB? Explain. Hypothesize the problems a mutant bacterium would have if they were unable to produce functional Min proteins. Would this mutant be easy or difficult to isolate and grow? Explain.
