Operon: A set of genes transcribed under the control of an operator gene. More specifically, an operon is a segment of DNA containing adjacent genes including structural genes, an operator gene, and a regulatory gene.
The best-studied examples of operons are from the bacterium Escherichia coli (E. coli), and they involve the enzymes of lactose metabolism and tryptophan biosynthesis. Because the lactose (lac) operon shares many features with other operons, its organization and regulation are described in detail below.ogether, these gene products act to import lactose into cells and break it down for use as a food source. As in other operons, the genes of the lac operon lie along a contiguous stretch of DNA such that their expression can be easily coregulated.
