  2. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    The replication fork is a structure that forms within the long helical DNA during DNA replication. It is produced by enzymes called helicases that break the hydrogen bonds that hold the DNA strands together in a helix.

  3. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    The process of semiconservative replication for the site of DNA replication is a fork-like DNA structure, the replication fork, 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. [3]

  5. Helicase - Wikipedia

    en.wikipedia.org/wiki/Helicase

    RecQ is a family of DNA helicase enzymes that are found in various organisms including bacteria, archaea, and eukaryotes (like humans). These enzymes play important roles in DNA metabolism during DNA replication, recombination, and repair. There are five known RecQ helicase proteins in humans: RecQ1, BLM, WRN, RecQ4, and RecQ5.

  6. DNA polymerase III holoenzyme - Wikipedia

    en.wikipedia.org/wiki/DNA_polymerase_III_holoenzyme

    DNA polymerase III synthesizes base pairs at a rate of around 1000 nucleotides per second. [3] DNA Pol III activity begins after strand separation at the origin of replication. Because DNA synthesis cannot start de novo, an RNA primer, complementary to part of the single-stranded DNA, is synthesized by primase (an RNA polymerase): [citation ...

  7. Primase - Wikipedia

    en.wikipedia.org/wiki/Primase

    DNA primase is an enzyme involved in the replication of DNA and is a type of RNA polymerase. Primase catalyzes the synthesis of a short RNA (or DNA in some living organisms [ 1 ] ) segment called a primer complementary to a ssDNA (single-stranded DNA) template.

  8. DNA polymerase - Wikipedia

    en.wikipedia.org/wiki/DNA_polymerase

    A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex. During this process, DNA polymerase ...

  9. Flap endonuclease - Wikipedia

    en.wikipedia.org/wiki/Flap_endonuclease

    Flap endonucleases (FENs, also known as 5' durgs in older references) are a class of nucleolytic enzymes that act as both 5'-3' exonucleases and structure-specific endonucleases on specialised DNA structures that occur during the biological processes of DNA replication, DNA repair, and DNA recombination.
