cistron

 [sis´tron]
the smallest unit of genetic material that must be intact to function as a transmitter of genetic information; as traditionally construed, approximately synonymous with gene.

cis·tron

(sis'tron),
1. The smallest functional unit of heritability; a length of chromosomal DNA associated with a single biochemical function. Under classical concepts, a gene might consist of more than one cistron; in modern molecular biology, the cistron is essentially equivalent to the structural gene.
2. The genetic unit defined by the cis/trans test.
[cis tr-ans + -on]

cistron

/cis·tron/ (sis´tron) the smallest unit of genetic material that must be intact to transmit genetic information; traditionally synonymous with gene.

cistron

(sĭs′trŏn′)
n.
A section of DNA that contains the genetic code for a single polypeptide and functions as a hereditary unit.

cis·tron′ic adj.

cistron

[sis′tron]
Etymology: L, cis, this side, trans, across
a fragment or portion of DNA that codes for a specific polypeptide. It is the smallest unit functioning as a transmitter of genetic information. In modern molecular genetics the cistron is essentially synonymous with the gene. It can include regions preceding and following the coding DNA as well as introns. -cistronic, adj.

cistron

A short length of DNA that codes for a protein subunit (a polypeptide), together with adjacent sequences that control its expression. It is the smallest unit that transmits genetic information.

cistron

or

functional gene

a portion of DNA coding for one POLYPEPTIDE CHAIN or other gene product. The one gene/ one enzyme hypothesis thus becomes the ‘one cistron (gene)/one polypeptide’ hypothesis or ‘one gene/one functional product’ hypothesis.

cistron

a DNA segment corresponding to one polypeptide chain plus the start-and-stop codon. The smallest unit of genetic material that must be intact to function as a transmitter of genetic information; as traditionaly construed, approximately synonymous with gene.
