  2. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    At the replication fork, many replication enzymes assemble on the DNA into a complex molecular machine called the replisome. The following is a list of major DNA replication enzymes that participate in the replisome: [46]

  3. 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 ...

  4. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    During DNA replication, the replisome will unwind the parental duplex DNA into a two single-stranded DNA template replication fork in a 5' to 3' direction. The leading strand is the template strand that is being replicated in the same direction as the movement of the replication fork.

  5. Replisome - Wikipedia

    en.wikipedia.org/wiki/Replisome

    DNA is a duplex formed by two anti-parallel strands. Following Meselson-Stahl, the process of DNA replication is semi-conservative, whereby during replication the original DNA duplex is separated into two daughter strands (referred to as the leading and lagging strand templates). Each daughter strand becomes part of a new DNA duplex.

  6. 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.

  7. Okazaki fragments - Wikipedia

    en.wikipedia.org/wiki/Okazaki_fragments

    During DNA replication, the double helix is unwound and the complementary strands are separated by the enzyme DNA helicase, creating what is known as the DNA replication fork. Following this fork, DNA primase and DNA polymerase begin to act in order to create a new complementary strand.

  8. Deoxyribozyme - Wikipedia

    en.wikipedia.org/wiki/Deoxyribozyme

    Although RNA enzymes were discovered before DNA enzymes, the latter have some distinct advantages. DNA is more cost-effective, and DNA can be made with longer sequence length and can be made with higher purity in solid-phase synthesis. [30] Several studies have shown the usage of DNAzymes to inhibit influenza A and B virus replication in host ...

  9. DNA gyrase - Wikipedia

    en.wikipedia.org/wiki/DNA_gyrase

    DNA gyrase, or simply gyrase, is an enzyme within the class of topoisomerase and is a subclass of Type II topoisomerases [1] that reduces topological strain in an ATP dependent manner while double-stranded DNA is being unwound by elongating RNA-polymerase [2] or by helicase in front of the progressing replication fork.
