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 lactose (lac) operon from Escherichia coli: z, y, and a are structural genes; i is the lac repressor gene; p is the promoter site; and o is the operator site. Activation is believed to arise from the binding of a protein immediately adjacent to the promoter. group of distinct genes that are expressed and regulated as a unit. Each operon is a deoxyribonucleic acid (DNA) sequence that contains at least two regulatory sites, the promoter and the operator, and the structural genes that code for specific proteins (see illustration).
