Concept

Problem: In the absence of tryptophan,A. the inducer cannot bind trpO, so operon gene transcription occurs.B. the active repressor cannot bind trpO, so operon gene transcription is attenuated.C. the inactive repressor cannot bind trpO, so operon gene transcription occurs.D. the repressor binds the corepressor, and operon gene transcription occurs.E. the active repressor binds trpO, so operon gene transcription is repressed.

FREE Expert Solution

The tryptophan operon (trpO) is one of the operons present in the genome of bacteria, particularly, E. coli. This operon is normally turned on, and would thus, need a repressor to temporarily suspend expression.

In the absence of tryptophan,

A. the inducer cannot bind trpO, so operon gene transcription occurs.

B. the active repressor cannot bind trpO, so operon gene transcription is attenuated.

C. the inactive repressor cannot bind trpO, so operon gene transcription occurs.

D. the repressor binds the corepressor, and operon gene transcription occurs.

E. the active repressor binds trpO, so operon gene transcription is repressed.
