WebPrimase is the enzyme that synthesizes RNA primers, oligonucleotides that are complementarily bound to a nucleic acid polymer. Primase is required because DNA … WebThe DNA-polymerase can only add nucleotides on an existing strand of DNA, so the primer (located at ori - origin of replication) "fakes" a DNA strand with a couple of RNA nucleotides. It's just to get things going. The primer is always broken down and replaced by DNA at the end of the replication process.
