  2. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    Progress of replication forks is inhibited by many factors; collision with proteins or with complexes binding strongly on DNA, deficiency of dNTPs, nicks on template DNAs and so on. If replication forks get stuck and the rest of the sequences from the stuck forks are not copied, then the daughter strands get nick nick unreplicated sites.

  3. DNA re-replication - Wikipedia

    en.wikipedia.org/wiki/DNA_re-replication

    Further, these studies indicate that rereplication can result in an increase in aneuploidy, chromosomal fusions, and DNA breaks. [24] A thorough understanding of the regulatory replication mechanisms is important for the development of novel cancer treatments.

  4. Origin of replication - Wikipedia

    en.wikipedia.org/wiki/Origin_of_replication

    The origin of replication (also called the replication origin) is a particular sequence in a genome at which replication is initiated. [1] Propagation of the genetic material between generations requires timely and accurate duplication of DNA by semiconservative replication prior to cell division to ensure each daughter cell receives the full ...

  5. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    Eukaryotic DNA replication. Eukaryotic DNA replication is a conserved mechanism that restricts DNA replication to once per cell cycle. Eukaryotic DNA replication of chromosomal DNA is central for the duplication of a cell and is necessary for the maintenance of the eukaryotic genome.

  6. Molecular cloning - Wikipedia

    en.wikipedia.org/wiki/Molecular_cloning

    Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...

  7. Meselson–Stahl experiment - Wikipedia

    en.wikipedia.org/wiki/Meselson–Stahl_experiment

    It has been called "the most beautiful experiment in biology". [1] Meselson and Stahl decided the best way to trace the parent DNA would be to tag them by changing one of its atoms. Since nitrogen is present in all of the DNA bases , they generated parent DNA containing a heavier isotope of nitrogen than would be present naturally.

  8. Replication - Wikipedia

    en.wikipedia.org/wiki/Replication

    Replication (scientific method), one of the main principles of the scientific method, a.k.a. reproducibility Replication (statistics), the repetition of a test or complete experiment; Replication crisis; Self-replication, the process in which an entity (a cell, virus, program, etc.) makes a copy of itself

  9. D-loop replication - Wikipedia

    en.wikipedia.org/wiki/D-loop_replication

    D-loop replication is a proposed process by which circular DNA like chloroplasts and mitochondria replicate their genetic material. An important component of understanding D-loop replication is that many chloroplasts and mitochondria have a single circular chromosome like bacteria instead of the linear chromosomes found in eukaryotes.
