Question

Quizplus · Accepted Answer

The gene that codes for a protein capable of repressing an operon is called the regulator gene. It produces a repressor protein that binds to the operator region of the operon, preventing transcription of the structural genes. The other options (operator, structural locus, promoter, and terminator) are all elements of the operon itself, but do not code for a repressor protein.
