When there is a large presence of tryptophan,what effect that does that have on the Trp repressor?

Question

Quizplus · Accepted Answer

When there is a large presence of tryptophan, it binds to the Trp repressor protein, causing a conformational change that allows it to bind to the operator region of the operon. This binding blocks RNA polymerase from transcribing the genes of the operon, resulting in repression of the operon. Therefore, the trp repressor is bound.
