What is the main function of RNA polymerase?
Posted October 15, 2021
The main function of RNA polymerase is to transcribe RNA molecules using DNA as a template.
RNA polymerase is a multi-unit intermediary enzyme that plays a key role in the transcription process during which the information stored in a DNA molecule is copied into a new molecule of mRNA (messenger RNA).
During the transcription process, RNA polymerase binds to the promoter region of the DNA strand and synthesizes a new strand of RNA. The new RNA strand is complementary to the DNA. The transcription of genetic information into RNA is the first step in gene expression. It is followed by translation, which is the process of decoding RNA into proteins.
