Kane Campos · Answer 1

low tryptophan concentration

Explanation:

The trp operon is a set of genes present in the bacteria which are involved in the synthesis of the tryptophan amino acid in the cell.

The trp operon is usually switched off when the tryptophan amino acid is present in the environment which is utilized by the bacteria but when the tryptophan level in the environment is reduced than the bacteria activates the trp operon.

The trp operon synthesizes the enzymes involved in the biosynthesis of tryptophan.

Thus, the selected option is correct.
