WebReplication initiation in all organisms involves the interaction of initiator proteins with one or more origins of replication in the DNA, with subsequent regulated assembly of two replisome complexes at each origin, melting of the DNA, and primed initiation of DNA synthesis on leading and lagging strands. WebMar 5, 2024 · In either situation, DNA replication is initiated at sites called origins of replication. These are regions of the DNA molecule that are recognized by special origin recognition proteins that bind the DNA. The binding of these proteins helps open up a region of single-stranded DNA where the synthesis of new DNA can begin.
