WebJan 1, 2024 · The primase component of the enzyme makes a short RNA strand (∼10 nucleotides), which is then transferred to the active site of Pol α. Pol α adds an additional 20 or so deoxyribonucleotides to the RNA strand. Thus in eukaryotes, the single-stranded primer for DNA replication is an RNA-DNA hybrid molecule. WebPrimase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis. Since primase produces R...

WebPrimase is an enzyme that plays a role in the beginning stages of replication. It does not contribute to the extension of either the lagging or the leading strand. The synthesis of RNA primers, which are necessary for the beginning of the DNA replication process, is catalyzed by the enzyme primase, which binds to the DNA at the origin of replication (ORI).
