Adjective
polycistronic (comparative more polycistronic, superlative most polycistronic)
(genetics, of mRNA) Encoding multiple different polypeptides.
The number of introns present in a cDNA is zero, since it is derived from eukaryotic mRNA which does not contain introns (polycistronic). Source: Internet
The operon is said to be polycistronic, whereas ordinary genes are said to be monocistronic. Source: Internet
Many viruses also produce their proteins initially as a single polypeptide chain that were translated from a polycistronic mRNA. Source: Internet
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). Source: Internet
