Question (i) Why was it expected that most of the colonies would be white?

Question (ii) Describe two different mutations mapping within protein-coding DNA that can account forthe blue colonies. The two mutations should map in different genes and need not map to the lacoperon. Name the gene with the mutation and explain how the mutation alters the function ofthe protein and thereby yields blue colonies.

Question (iii) Describe two different mutations that do NOT map within a protein-coding region thatcan account for the blue colonies. The two mutations should affect distinct aspects of lacregulation.

Question (iv) Predict whether each of your four mutations would be dominant or recessive to wild-type.Explain briefly.
