Question 12 of 15 What is the role of tryptophan in the regulation of the trp operon? When tryptophan levels are low, tryptophan inactivates the trp repressor. When tryptophan levels are high, tryptophan binds to the inactive trp repressor, making it active. When tryptophan levels are high, tryptophan binds to RNA polymerase to stimulate transcription. When tryptophan levels are high, tryptophan stimulates the transcription of the trp regulatory gene. When tryptophan levels are low, tryptophan stimulates the transcription of the structural genes.
