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.
- Bacteria often respond to environmental change by regulating transcription. - Gene expression in bacteria is controlled by the operon model. A. Operons: The Basic Concept-A cluster of functionally related genes can be under coordinated control by a single on-off âswitchâ.- The regulatory âswitchâ is a segment of DNA called an operator usually positioned within the promoter. Almost all the cells in an organism are genetically identical. - Differences between cell types result from differential gene expression, the. expression of different genes by cells with the same genome. - Errors in gene expression can lead to diseases including cancer.
