Replication Fork | Science Primer
https://scienceprimer.com/replication-fork
The replication fork is a region where a cell's DNA double helix has been unwound and separated to create an area where DNA polymerases and the other enzymes involved can use each strand as a template to synthesize a new double helix. An enzyme called a helicase catalyzes strand separation.

Specialized proteins recognize the origin, bind to this site, and open up the DNA. As the DNA opens, two Y-shaped structures called replication forks are formed, together making up what's called a replication bubble. The replication forks will move in opposite directions as replication proceeds.

Jan 29, 2013 · The process of semiconservative replication suggested a geometry for the site of DNA replication, a fork-like DNA structure, where the DNA helix is open, or unwound, exposing unpaired DNA nucleotides for recognition and base pairing for the incorporation of free nucleotides into double-stranded DNA ( Figure 1 ).

The RF is a multiprotein complex with helicase and DNA synthesis activities. It is called a fork because the structure resembles a two-pronged fork. The helicase activities unwind DNA in front...

The replication fork is the branched (forked) DNA at either end of the replication bubble. The replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit.

Mar 17, 2022 · As the DNA opens up, Y-shaped structures called replication forks are formed (Figure \(\PageIndex{3}\)). Two replication forks are formed at the origin of replication, and these get extended in both directions as replication proceeds.

Oct 31, 2023 · As the DNA opens up, Y-shaped structures called replication forks are formed. Because two helicases bind, two replication forks are formed at the origin of replication; these are extended in both directions as replication proceeds creating a replication bubble.

The replication fork is a Y-shaped active region where two strands of DNA are separated and replicated continuously. The coupling of DNA unzipping and complementary strand synthesis is a characteristic feature of a replication fork.
