(Biyokimya) operon
A unit of genetic material that functions in a coordinated manner by means of an operator, a promoter, and structural genes that are transcribed together
The sequence of bases in DNA that contains one or more structural genes together with the operator controlling their expression (See 277)
A set of genes transcribed under the control of an operator gene Source : Human Genome Project Information
A set of adjacent structural genes in bacteria whose mRNA is synthesized in one piece, together with the adjacent regulatory signals that affect transcription of the structural genes A sequence of adjacent bacterial genes all under the transcriptional control of the same operator
A set of genes transcribed under the control of an operator gene
A prokaryotic DNA region that coordinates the regulatory and structural sequences for a gene or set of related genes
a segment of DNA containing adjacent genes including structural genes and an operator gene and a regulatory gene
Sequence of genes responsible for synthesizing the enzymes needed for biosynthesis of a molecule An operon is controlled by an operator gene and a repressor gene
Genetic regulatory system of single-celled organisms (prokaryotes) and their viruses, in which genes coding for functionally related proteins are clustered along the DNA, enabling their expression to be coordinated in response to the cell's needs. By providing a means to produce proteins only when and where they are required, the operon allows the cell to conserve energy. A typical operon consists of a group of structural genes that code for enzymes involved in a metabolic pathway, such as the biosynthesis of an amino acid. A single unit of messenger RNA is transcribed from the operon and is then translated into separate proteins. Operons are controlled by various regulatory elements that respond to environmental cues. The operon system was first proposed by François Jacob and Jacques Monod in the early 1960s
A cluster of genes whose expression is controlled by a single operator Typical of prokaryotic cells
Transcriptional unit including cis-acting control elements and structural genes
A cluster of genes whose expressions are regulated together by operator-regulator protein interactions, plus the operator region itself and the promoter
