Eukaryotic replication fork

Initiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase α occurs on the leading strand. The priming event on the lagging strand establishes a replication fork. Priming of the DNA helix consists of synthesis of an RNA primer to allow DNA synthesis by DNA polymerase α.
