DNA Primase
Definition 1
Heterodimeric human DNA Primase consists of a 49-kDa (small) and a 58-kDa (large) subunit. Eukaryotic DNA replication involves a replication apparatus containing the key enzymatic components DNA Primase and DNA Polymerase Alpha. DNA Primase is a polymerase that synthesizes small RNA primers for Okazaki fragments made during discontinuous DNA replication. (NCI Thesaurus)
Definition 2
A single-stranded DNA-dependent RNA polymerase that functions to initiate, or prime, DNA synthesis by synthesizing a nucleotide RNA polymer. EC 2.7.7.-. (NLM, Medical Subject Headings)
