The statement describing the operon is D. It is deactivated whenever tryptophan is added to the growth medium.

Operons are groups of structural genes that are expressed in a coordinated manner and are simultaneously under the control of a single regulatory signal. This makes the process of genetic expression in cells more efficient because nerve disorders are involved in the same series of metabolic reactions.

Some prokaryotes use the tryptophan operon system to control gene expression. In the tryptophan operon, the operons are transcribed together to code for components required in the production of the amino acid tryptophan. The mechanism of this operation is controlled by suppression of the end products of expression and attenuation. In some bacteria, controlling gene expression uses negative control involving the activity of a regulatory gene. This operon will be deactivated whenever tryptophan is added to the growth medium so that the process of genetic expression in cells is more efficient.
