  2. Semiconservative replication - Wikipedia

    en.wikipedia.org/wiki/Semiconservative_replication

    Semiconservative replication describes the mechanism of DNA replication in all known cells. DNA replication occurs on multiple origins of replication along the DNA template strands. As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi ...

    However, this result was consistent with both semiconservative and dispersive replication. Semiconservative replication would result in double-stranded DNA with one strand of 15 N DNA, and one of 14 N DNA, while dispersive replication would result in double-stranded DNA with both strands having mixtures of 15 N and 14 N DNA, either of which ...

  4. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    Eukaryotes initiate DNA replication at multiple points in the chromosome, so replication forks meet and terminate at many points in the chromosome. Because eukaryotes have linear chromosomes, DNA replication is unable to reach the very end of the chromosomes. Due to this problem, DNA is lost in each replication cycle from the end of the chromosome.

  5. 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]

  6. Prokaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Prokaryotic_DNA_replication

    Prokaryotic DNA Replication is the process by which a prokaryote duplicates its DNA into another copy that is passed on to daughter cells. [1] Although it is often studied in the model organism E. coli, other bacteria show many similarities. [2] Replication is bi-directional and originates at a single origin of replication (OriC). [3]

    A man whose conviction for a 1994 murder was overturned on new DNA evidence says he's having a hard time adjusting to today's hyper-connected world after spending the past 30 years behind bars.

  9. Replisome - Wikipedia

    en.wikipedia.org/wiki/Replisome

    The replication of bacteriophage T4 DNA upon infection of E. coli is a well-studied DNA replication system. During the period of exponential DNA increase at 37°C, the rate of elongation is 749 nucleotides per second. [11] The mutation rate during replication is 1.7 mutations per 10 8 base pairs. [12]
