Primase is an enzyme that makes

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...
