Single-strand binding proteins bind to the single-stranded DNA near the replication fork to keep the fork open. The study of replication in prokaryotes has formed the basis of our understanding of replicative mechanisms common to all organisms. Escherichia coli (E. coli) is an excellent bacterial system that can be used to study the three distinct stages of DNA replication: initiation, elongation and termination.
