TRP operon will always be on.

The trp operon is an illustration of a repressible system, which means that the operon switches on automatically unless a repressor becomes active and deactivates it.
A collection of genes known as the trp operon is discovered in the bacteria E. coli and codes for enzymes that produce the amino acid tryptophan.
When tryptophan levels are low, the trp operon is expressed (or "turned on") and is repressed (or "shut off") when levels are high.
The trp repressor controls the activity of the trp operon. The trp repressor prevents expression of the operon when it is linked to tryptophan.
When tryptophan levels are low, the trp operon is expressed (or "turned on") and is repressed (or "shut off") when levels are high. The trp repressor controls the activity of the trp operon.
