Health

The genetic unit consisting of a feedback system under the control of an operator gene, in which a structural gene transcribes its message in the form of mRNA upon blockade of a repressor produced by a regulator gene. Included here is the attenuator site of bacterial operons where transcription termination is regulated. (references)

Medicine

A group of closely linked genes responsible for the synthesis of a group of enzymes which are functionally related as members of one enzyme system. It comprises an operator region, a number of structural genes and a regulator gene. Source: European Union. (references)

Specialty Definition: Operon

(From Wikipedia, the free Encyclopedia)

An operon is a collection of inter-related genes including one which acts as a switch that governs the expression of the structural genes in the collection. Structural genes are those that encode a product. Operons, which occur primarily in prokaryotes and nematodes, allow cells to respond to their environment. They were first described by François Jacob and Jacques Monod in 1961.

The operon as a unit of transcription

An operon is a unit of transcription consisting of one or more structural genes, and two associated segments of DNA:

The switch of an operon (that is, the "operator") is turned on unless a specific substance is bound to the operator. This substance is therefore called a repressor.

In summary:

Example: Lac operon

The lac operon governs the production of enzymes for metabolizing lactose. In the absence of lactose, the repressor substance binds to the operator, inhibiting the production of three enzymes. Lactose, however, represses the repressor, allowing the enzymes to be produced.
