polycistronic
Adjective
Meaning
polycistronic (comparative more polycistronic, superlative most polycistronic)
(genetics, of mRNA) Encoding multiple different polypeptides.
Examples
The number of introns present in a cDNA is zero, since it is derived from eukaryotic mRNA which does not contain introns (polycistronic).
The operon is said to be polycistronic, whereas ordinary genes are said to be monocistronic.
Many viruses also produce their proteins initially as a single polypeptide chain that were translated from a polycistronic mRNA.
Monocistronic versus polycistronic mRNA seeAlso An mRNA molecule is said to be monocistronic when it contains the genetic information to translate only a single protein chain (polypeptide).
