RNA polymerase - Wikipedia
In molecular biology, RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is an enzyme that catalyzes the chemical reactions that synthesize RNA from a DNA template.
RNA Polymerase - Definition, Function and Types - Biology …
2019年3月14日 · A RNA polymerase (RNAP), or ribonucleic acid polymerase, is a multi subunit enzyme that catalyzes the process of transcription where an RNA polymer is synthesized from a DNA template.
RNA Polymerase - Definition, Types, Structure, and Functions
2023年11月7日 · The RNA polymerase is primarily responsible for transcription, the process by which a template DNA strand is used to form RNA. RNA polymerase produces all types of RNA, including messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), microRNA (miRNA), and even non-coding RNAs and ribozymes.
