Which of the following is true about the regulation of the trp operon?

Question

Quizplus · Accepted Answer

All of the choices are true about the regulation of the trp operon. An aporepressor (the inactive form of a repressor) is involved in controlling the trp operon. Tryptophan, the product of the operon, acts as a corepressor, binding to the aporepressor and activating it to bind to the operator region and inhibit transcription. Attenuation, a mechanism that regulates transcription by premature termination of mRNA synthesis, also plays a role in controlling the trp operon. Finally, the regulation of the trp operon involves negative control, where a repressor protein binds to the operator and prevents transcription.
