WebNov 14, 2024 · RNA polymerase is an enzyme that produces RNA and catalyzes the initiation and elongation of RNA chains from a DNA template. RNA is created using a process known as transcription. The RNA polymerase is a key component to this process. The reaction that this enzyme catalyzes for is: (RNA)n + Ribonucleoside Triphosphate ->/< … WebJul 31, 2016 · Conclusion. RNA polymerase does not play a role in DNA replication, it plays a role in DNA transcription. RNA polymerase makes mRNA from DNA. Note that enzymes that replicate RNA are called RNA replicases. In line with this it would make sense to call DNA polymerase, DNA replicase. This is technically correct, but the term is rarely used.
