Anatomy of a DNA replication fork revealed by reconstitution of SV40 DNA replication in vitro

S Waga et al. Nature. 1994.

Abstract

Complete enzymatic replication of DNA from the simian virus 40 origin has been reconstituted with T antigen and highly purified cellular proteins. DNA polymerase-alpha/primase functions primarily to synthesize RNA-DNA primers for initiation of DNA replication at the origin and for priming each Okazaki fragment. A polymerase switching mechanism requiring replication factor C and the proliferating cell nuclear antigen allows two molecules of DNA polymerase-delta to replicate both strands of the double helix conjointly.
