They contain promoters and operators that determine when a gene is transcribed.

Explanation: An operon is a cluster of genes plus regulatory sequences (promoter, operator) that control whether RNA polymerase transcribes the structural genes (e.g., lac operon). It does not transfer mRNA to ribosomes or unzip DNA.
