Answer:
Tryptophan synthesis enzymes be made during low level of cellular tryptophan.
Explanation:
Tryptophan operon contain 3 regulatory gene(trpR,trpP and trpO) and 5 structural genes(trpE,trpD,trpC,trpB and trpA) .trpR encodes the repressor protein that interacts with tryptophan present in the media and then the tryptophan repressor complex binds to the operator region to block the transcription of the structural genes of tryptophan operon.
Here tryptophan acting as a corepresor.During mutation of trpR gene tryptophan biosynthesis enzymes will be synthesized only when the cellular tryptophan level remains very low.
