Think about the trp operon. For each situation below, indicate whether the cell will synthesize the enzymes coded by trpE, trpD, trpC, trpB, and trpA and be able to synthesize trypophan.
Can tryptophan be synthesized in the cell for the following (yes or no answer):
A mutation in the promoter: RNA polyermase cannot bind.
A mutation in the operator: cannot bind the repressor.
A mutation in trpR: its product (the repressor) is nonfunctional.
A mutation in trpD: the enzyme product is inactive.
