  2. DNA polymerase - Wikipedia

    en.wikipedia.org/wiki/DNA_polymerase

    A DNA polymeraseis a member of a family of enzymesthat catalyze the synthesis of DNAmoleculesfrom nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replicationand usually work in groups to create two identical DNA duplexes from a single original DNA duplex. During this process, DNA polymerase "reads ...

  3. DNA polymerase I - Wikipedia

    en.wikipedia.org/wiki/DNA_polymerase_I

    Domains. InterPro. DNA polymerase I (or Pol I) is an enzyme that participates in the process of prokaryotic DNA replication. Discovered by Arthur Kornberg in 1956, [ 1 ] it was the first known DNA polymerase (and the first known of any kind of polymerase). It was initially characterized in E. coli and is ubiquitous in prokaryotes.

  4. Polymerase - Wikipedia

    en.wikipedia.org/wiki/Polymerase

    Structure of Taq DNA polymerase. In biochemistry, a polymerase is an enzyme (EC 2.7.7.6/7/19/48/49) that synthesizes long chains of polymers or nucleic acids. DNA polymerase and RNA polymerase are used to assemble DNA and RNA molecules, respectively, by copying a DNA template strand using base-pairing interactions or RNA by half ladder replication.

  5. DNA polymerase III holoenzyme - Wikipedia

    en.wikipedia.org/wiki/DNA_polymerase_III_holoenzyme

    This is the old textbook "trombone model" with two units of Pol III. DNA polymerase III holoenzyme is the primary enzyme complex involved in prokaryotic DNA replication. It was discovered by Thomas Kornberg (son of Arthur Kornberg) and Malcolm Gefter in 1970. The complex has high processivity (i.e. the number of nucleotides added per binding ...

  6. Polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Polymerase_chain_reaction

    A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.

  7. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    The double-stranded structure of DNA provides a simple mechanism for DNA replication. Here, the two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase. This enzyme makes the complementary strand by finding the correct base through complementary base pairing and bonding it onto ...

  8. DNA synthesis - Wikipedia

    en.wikipedia.org/wiki/DNA_synthesis

    DNA synthesis is the natural or artificial creation of deoxyribonucleic acid (DNA) molecules. DNA is a macromolecule made up of nucleotide units, which are linked by covalent bonds and hydrogen bonds, in a repeating structure. DNA synthesis occurs when these nucleotide units are joined to form DNA; this can occur artificially (in vitro) or ...

  9. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    DNA polymerase catalysis and specific nucleotide labeling, both of which figure prominently in current sequencing schemes, were used to sequence the cohesive ends of lambda phage DNA. [ 34 ] [ 35 ] [ 36 ] Between 1970 and 1973, Wu, R Padmanabhan and colleagues demonstrated that this method can be employed to determine any DNA sequence using ...
