Indicates the replication fork

Web29 okt. 2012 · Chromosomal origins of replication require the assembly of two replication forks and hence two replicative polymerases must be loaded at each origin. Bacterial and bacteriophage replicative helicases are loaded onto ssDNA and translocate in the 5′–3′ direction [ 8 ] as does the human mitochondrial replicative helicase Twinkle [ 9 ]. WebThe replication fork is a structure that forms within the long helical DNA during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together in the helix. The resulting structure has two branching "prongs", each one made up of a single strand of DNA.

Its unique DNA-binding property allows it to recognize and stabilize stalled forks and the structures derived from them. The replication fork is a structure which is formed during the process of DNA replication.
