Based upon what you have learned about the coli trp operon, what could you say about expression of its structural genes in cells with large amounts of environmental trp, but lacking the leader and attenuator sequences?

The mannitol operon regulates expression of genes whose protein products are needed for mannitol catabolism. The operon is expressed when mannitol is present and glucose is absent, but not when mannitol is absent or when glucose is present. What would most likely happen if the bacterial environment contains mannitol, lacks glucose, and contains an inhibitor of adenylyl cyclase?
