Lac Operon | Virtual Cell Animation Collection The E. coli lac operon is an example of an inducible set of genes. These genes are responsible for the breakdown of lactose into sugars used for cellular metabolism. This inducible system also involves bacterial DNA, a repressor, mRNA, and the sugar molecule lactose. This animation will only focus on two of the three proteins encoded by the lac ... Lac Operon : Advanced Look --> 1.) The Repressor An operon is a series of genes linked together on the bacterial chromosome that are activated by a single promoter and produce a single mRNA molecule. Expression of the genes is turned off when a protein called the repressor binds to the promoter (red) and operator (orange) of the operon. Lactose must be added to to activate the lac operon.

Lac Operon: Diagram, Phenotypes, Model, and Regulation Lac operon is an abbreviated form of lactose operon. Lactose operon is used for transporting and metabolising the lactose in E. coli and many other enteric bacteria. Though glucose is considered a preferred carbon source for most bacteria, the activity of operon allows for the digestion of lactose effectively when the glucose is not available through the activity of the beta-galactosidase.

The lac operon (article) | Khan Academy The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent. Two regulators turn the operon "on" and "off" in response to lactose and glucose levels: the lac repressor and catabolite activator protein (CAP). The lac repressor acts as a lactose sensor.
