Suppose you had a bacteriophage λ in which the gene encoding the cro protein had been mutated, so that it had an unusually high affinity for pL - in this phage the first promoter repressed by cro would be pL, not pRM. What effect, if any, would this mutation, and the consequent rapid repression of transcription from pL, have on the outcome of a cell being infected by this mutant bacteriophage? Explain why you would predict that outcome of an
infection by this mutant phage.
