WebM.A. Griep, in Brenner's Encyclopedia of Genetics (Second Edition), 2013 Abstract. Primase is the enzyme that synthesizes RNA primers, oligonucleotides that are complementarily bound to a nucleic acid polymer. Primase is required because DNA polymerases cannot initiate polymer synthesis on single-stranded DNA templates; they …
