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.
The lactose (lac) operon from Escherichia coli: z, y, and a are structural genes; i is the lac repressor gene; p is the promoter site; and o is the operator site. Activation is believed to arise from the binding of a protein immediately adjacent to the promoter. group of distinct genes that are expressed and regulated as a unit. Each operon is a deoxyribonucleic acid (DNA) sequence that contains at least two regulatory sites, the promoter and the operator, and the structural genes that code for specific proteins (see illustration).
