WebDNA replication is catalyzed by several enzymes that play specific roles. DNA polymerase adds new nucleotides to the newly growing strand, RNA primase synthesizes the RNA primer that serves as the starting point for new strand synthesis, helicase unwinds the double helix and forms the replication fork, gyrase and topoisomerase prevent ... Web29 jul. 2024 · Helicase unwinds the DNA, and then an enzyme called polymerase copies it into an RNA molecule. As RNA polymerase passes by, the DNA naturally zips back up behind it since the base pairs would prefer not to be exposed to the watery cell environment. During DNA transcription, the double helix opens up in a "bubble" (Image via Shutterstock)
