Gene Regulation and the Lac Operon

| Description | Prokaryotic cells, such as bacterial cells, regulate and control their genetic expression by using the operon model. An operon is the smallest unit of control. It consists of a segment of DNA that contains two important sections, the regulatory section and the coding section. The regulatory section is a sequence of DNA that contains the control sites, such as the promoter site and the operator site. The coding section contains the genes that code for the actual proteins that are used by the cell. Adjacent to the operon is the gene that codes for the activator or repressor protein that is involved with that particular operon. This regulatory gene usually contains its own promoter region. The prototypical example of the operon is the Lac operon that is used by E. Coli. The Lac operon contains the genes and regulatory sites that are responsible for breaking down lactose into glucose and galactose. |
