1977 R. McMacken et al. in Proc. National Acad. Sci. U.S.A. 74 4190/1 Among the single-stranded..phage DNAs thus far tested in replication systems in vitro, the ϕX174 class is unique in being converted first to a multiprotein intermediate..to enable the synthesis of a primer by dnaG protein (primase).

1986 Ann. Rev. Biochem. 55 760 Primase synthesizes 5′-terminal oligoribonucleotides of discrete length, about 10 nucleotides, and of random sequence.

1995 D. Kipling Telomere iv. 92 As Okazaki fragments are around 200 nucleotides in length, this implies that primase synthesizes RNA primers spaced roughly this distance apart.
