    Rif1 inhibits replication fork progression and controls DNA copy number in Drosophila

    Alexander Munden et al.
    To regulate DNA copy number during development in Drosophila, the SUUR protein recruits Rif1 to replisomes where Rif1 inhibits replication fork progression, thus controlling copy number independently of origin firing.

    DNA-mediated association of two histone-bound complexes of yeast Chromatin Assembly Factor-1 (CAF-1) drives tetrasome assembly in the wake of DNA replication

    Francesca Mattiroli et al.
    After DNA replication, nucleosomes are assembled by two histone chaperone complexes each bound to an H3-H4 histone dimer, suggesting the feasibility for a semi-conservative mode of epigenome inheritance.

    Frequent exchange of the DNA polymerase during bacterial chromosome replication

    Thomas R Beattie et al.
    DnaB Helicase is the only stable component of the bacterial replisome as the replicative DNA polymerase frequently exchanges in both leading and lagging strands.

    Two subunits of human ORC are dispensable for DNA replication and proliferation

    Etsuko Shibata et al.
    Human cell lines replicate and proliferate without ORC1 or ORC2, two subunits of the replication initiator protein complex ORC, which has till now been considered essential for DNA replication.

    Cdc6 ATPase activity disengages Cdc6 from the pre-replicative complex to promote DNA replication

    FuJung Chang et al.
    Biochemical and genetic characterization of the Cdc6 replication initiator reveals similarities in the helicase loading reaction between bacteria and eukaryotes.

    Single-molecule studies contrast ordered DNA replication with stochastic translesion synthesis

    Gengjing Zhao et al.
    Competing DNA polymerases at the DNA sliding clamp are revealed by single-molecule co-localization studies.

    Rapid DNA replication origin licensing protects stem cell pluripotency

    Jacob Peter Matson et al.
    The unique cell cycle variations of pluripotent stem cells ensures that the first step in DNA replication is particularly fast and this rapid rate, in turn, restrains early differentiation.

    DNA Replication: Rethinking origin licensing

    Stephen P Bell
    Human cells that lack a subunit in their origin recognition complex are viable, which suggests the existence of alternative mechanisms to initiate DNA replication.

    DNA Replication: A new role for a tumor-suppressing protein

    Jeremy S Setton, Simon N Powell
    In addition to its role in preventing tumors, the protein p53 appears to participate in a DNA repair process known as the replication-stress response.

    Multiple kinases inhibit origin licensing and helicase activation to ensure reductive cell division during meiosis

    David V Phizicky et al.
    Meiotic cells inhibit two distinct steps of replisome assembly with multiple kinases to prevent DNA replication between Meiosis I and Meiosis II.
