DNA primase large subunit is an enzyme that in humans is encoded by the PRIM2 gene.The replication of DNA in eukaryotic cells is carried out by a complex chromosomal replication apparatus in which DNA polymerase alpha and primase are two key enzymatic components. Primase which is a heterodimer of a small subunit and a large subunit synthesizes small RNA primers for the Okazaki fragments made during discontinuous DNA replication.
