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 organization of genes into an operon allows for simultaneous expression of all the genes that are located in cis (i.e., on the same contiguous piece of DNA) in the operon. Several features contribute to this characteristic of operons (Figure 1). First, all of the operon's genes are downstream of a single promoter.
