Question

If a mutation occurred in the trp operator that prevented the repressor from binding, what would be the most likely outcome?

Tryptophan synthesis would occur even in the presence of tryptophan.

The operon would always remain in an off state.

Answer

Tryptophan would be degraded rapidly due to a malfunction in its regulation.

Answer

The repressor would bind more tightly to the operator region.
