Lac operon

SOLVED: An E. coli cell undergoes a frameshift mutation in the gene that codes for the lac repressor proteina) Describe what happened to cause this mutation and how it might have occurred b) Would you expect this mutation to affect the lac genes? Explain fully: c) Assume the mutation makes the repressor protein non-functional: In what way would this cell react differently than a normal E. coli cell to a sudden increase in the concentration of lactose in it's environment?
