3 Structural gene clusters are coordinately controlled. 1  An operon is a unit of bacterial gene expression and regulation, including structural genes and control elements in DNA recognized by regulator gene product(s).acterial structural genes are often organized into clusters that include genes coding for proteins whose functions are related.
Concept 3: The lac Operator. The operator is a short region of DNA that lies partially within the promoter and that interacts with a regulatory protein that controls the transcription of the operon. Here's an analogy. A promoter is like a doorknob, in that the promoters of many operons are similar. An operator is like the keyhole in a doorknob, in that each door is locked by only a specific key, which in this analogy is a specific regulatory protein.
