WebMar 25, 2024 · RNA polymerase function. RNA polymerase (RNApol) is a multi-unit enzyme that is responsible for creating a complimentary strand of nucleic acid, called RNA, from a single stranded DNA template through the incorporation of adenosine, cytosine, guanine and uracil nucleotides. The process by which this occurs is called transcription.
