WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. WebSep 5, 2024 · An RNA primer is essentially just a short strand of RNA bases, usually around 20 bases long, that is needed by DNA polymerase to start replication. Now DNA polymerase is ready to go to work.
