WebMar 21, 2006 · This involves templated synthesis of ∼20 base pairs of DNA twice at each replication origin to initiate leading-strand DNA synthesis and repeatedly (every ∼200 base pairs) to sustain lagging-strand synthesis. After primer synthesis, a switch occurs from polymerase α to the principal replicative polymerases δ and ɛ. WebSome other proteins and enzymes, in addition the main ones above, are needed to keep DNA replication running smoothly. One is a protein called the sliding clamp, which holds DNA polymerase III molecules in place as they synthesize DNA.The sliding clamp is a ring-shaped protein and keeps the DNA polymerase of the lagging strand from floating off …
