Rna polymerase

RNA polymerase

(Science: enzyme molecular biology) An enzyme that polymerise ribonucleotides in accordance with the information present in dNA.

prokaryotes have a single enzyme for the three rNA types that is subject to stringent regulatory mechanisms. Eukaryotes have type I that synthesises all rRNA except the 5S component, type II that synthesises mRNA and hnRNA and type III that synthesises tRNA and the 5S component of rRNA. An enzyme that contributes to the formation of RNA from DNA templates.
