  2. Matthew Meselson - Wikipedia

    en.wikipedia.org/wiki/Matthew_Meselson

    With Charles Radding, Meselson developed a model for recombination between DNA duplexes that guided research in the field for the decade from 1973 to 1983. [ 11 ] In 1961, Sydney Brenner , François Jacob and Meselson used the density-gradient method to demonstrate the existence of messenger RNA.

  3. Holliday junction - Wikipedia

    en.wikipedia.org/wiki/Holliday_junction

    An updated model by Matt Meselson and Charley Radding in 1975 introduced the idea of branch migration. [26] Further observations in the 1980s led to the proposal of alternate mechanisms for recombination such as the double-strand break model (by Jack Szostak, Frank Stahl, and others) and the single-strand annealing model. A third, the synthesis ...

    en.wikipedia.org/wiki/Semiconservative_replication

    Meselson-Stahl experiment using isotopes to discover semiconservative replication. Multiple experiments were conducted to determine how DNA replicates. The semiconservative model was anticipated by Nikolai Koltsov and later supported by the Meselson–Stahl experiment , [ 4 ] [ 5 ] which confirmed that DNA replicated semi-conservatively by ...

    en.wikipedia.org/wiki/Meselson–Stahl_experiment

    The Meselson–Stahl experiment is an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative. In semiconservative replication, when the double-stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from ...

  6. Franklin Stahl - Wikipedia

    en.wikipedia.org/wiki/Franklin_Stahl

    Glucos 6-phosphate dehydrogenase. Franklin (Frank) William Stahl (born October 8, 1929) is an American molecular biologist and geneticist. With Matthew Meselson, Stahl conducted the famous Meselson-Stahl experiment showing that DNA is replicated by a semiconservative mechanism, meaning that each strand of the DNA serves as a template for production of a new strand.

  9. Homologous recombination - Wikipedia

    en.wikipedia.org/wiki/Homologous_recombination

    Double-strand break repair models that act via homologous recombination. Two primary models for how homologous recombination repairs double-strand breaks in DNA are the double-strand break repair (DSBR) pathway (sometimes called the double Holliday junction model) and the synthesis-dependent strand annealing (SDSA) pathway.
