WebModel for eukaryotic DNA replication. In step 1, ORC and associated initiation factors bind to sites in the genome in G1 phase and catalyze pre-RC assembly. The distribution of pre-RCs is described by a probability distribution giving the likelihood of stable assembly at each genomic position.

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.
