  2. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    In various bacterial species, this is named the DNA replication terminus site-binding protein, or Ter protein. [citation needed] Because bacteria have circular chromosomes, termination of replication occurs when the two replication forks meet each other on the opposite end of the parental chromosome.

  3. Prokaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Prokaryotic_DNA_replication

    The rate of DNA replication in a living cell was first measured as the rate of phage T4 DNA elongation in phage-infected E. coli. [18] During the period of exponential DNA increase at 37 °C, the rate was 749 nucleotides per second. The mutation rate per base pair per replication during phage T4 DNA synthesis is 1.7 per 10 8. [19]

  4. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    The major enzymatic functions carried out at the replication fork are well conserved from prokaryotes to eukaryotes, but the replication machinery in eukaryotic DNA replication is a much larger complex, coordinating many proteins at the site of replication, forming the replisome.

  5. Circular chromosome - Wikipedia

    en.wikipedia.org/wiki/Circular_chromosome

    The E. coli origin of replication, called oriC consists of DNA sequences that are recognised by the DnaA protein, which is highly conserved amongst different bacterial species. DnaA binding to the origin initiates the regulated recruitment of other enzymes and proteins that will eventually lead to the establishment of two complete replisomes ...

  6. Bacterial DNA binding protein - Wikipedia

    en.wikipedia.org/wiki/Bacterial_DNA_binding_protein

    Histone-like proteins are present in many Eubacteria, Cyanobacteria, and Archaebacteria.These proteins participate in all DNA-dependent functions; in these processes, bacterial DNA binding proteins have an architectural role, maintaining structural integrity as transcription, recombination, replication, or any other DNA-dependent process proceeds.

  7. Origin of replication - Wikipedia

    en.wikipedia.org/wiki/Origin_of_replication

    More than five decades ago, Jacob, Brenner, and Cuzin proposed the replicon hypothesis to explain the regulation of chromosomal DNA synthesis in E. coli. [18] The model postulates that a diffusible, trans-acting factor, a so-called initiator, interacts with a cis-acting DNA element, the replicator, to promote replication onset at a nearby origin.

  8. Replicon (genetics) - Wikipedia

    en.wikipedia.org/wiki/Replicon_(genetics)

    The initiator is the protein that recognizes the replicator and activates replication initiation. [ 1 ] Sometimes in bacteriology , the term "replicon" is only used to refer to chromosomes containing a single origin of replication and therefore excludes the genomes of archaea and eukaryotes which can have several origins.

  9. Pre-replication complex - Wikipedia

    en.wikipedia.org/wiki/Pre-replication_complex

    A pre-replication complex (pre-RC) is a protein complex that forms at the origin of replication during the initiation step of DNA replication. Formation of the pre-RC is required for DNA replication to occur. Complete and faithful replication of the genome ensures
