Dna primase
Webprimase: ( prī'māz ), A polymerase that acts on a template DNA strand to produce RNA, resulting in the formation of an RNA primer needed in RNA replication. Synonym(s): … WebFeb 21, 2024 · Here, we report cryo-EM structures of polα-primase in complex with primed templates representing various stages of DNA synthesis. Our data show how interaction of the primase regulatory subunit with the primer 5'-end facilitates handoff of the primer to polα and increases polα processivity, thereby regulating both RNA and DNA composition.
