Predict the phenotype for expression of the E. coli trp operon enzymes for the following mutants: a) A to U mutation at position 48 of the trp operon leader RNA. b) Deletion from positions 114-121 of the trp operon leader RNA. Explain your predictions taking into account the alternate stem-loop structures of the leader RNA.
