The trp operon is classified as a:
Show answer and explanation
Correct answer: Repressible operon
The trp operon is repressible: it is active by default (transcribed when tryptophan is scarce) and turned off when tryptophan levels are high. Tryptophan binds to the inactive aporepressor, converting it into an active repressor that blocks the operator.
