The Tryptophan Operon Is a Repressible Operon That Is?

Answer

The tryptophan operon of the Escherichia coli or E. coli is responsible for controlling the biosynthesis of tryptophan in the cell from the initial precursor chorismic acid. The operon contains genes for the production of five proteins which are used to produce three enzymes.
