An operon consists of an operator, promoter, regulator, and structural genes.

Explanation:

Promoter – a nucleotide sequence that enables a gene to be transcribed. The promoter is recognized by RNA polymerase, which then initiates transcription. Operator – a segment of DNA to which a repressor binds.
