    Transposition-mediated DNA re-replication in maize

    Jianbo Zhang et al.
    Transposition reactions that occur during DNA replication and involve the termini of adjacent transposons can induce genome expansion by re-replication of transposon-flanking sequences.

    cryo-EM structures of the E. coli replicative DNA polymerase reveal its dynamic interactions with the DNA sliding clamp, exonuclease and τ

    Rafael Fernandez-Leiro et al.
    Structures of the replicative DNA polymerase Pol IIIα, the DNA sliding clamp, the proofreading exonuclease, and the processivity switch Tau (τ) suggest a mechanism for quick release during lagging strand synthesis.

    Loss of p53 suppresses replication-stress-induced DNA breakage in G1/S checkpoint deficient cells

    Bente Benedict et al.
    During tumorigenesis loss of p53 not only abrogates cell cycle arrest and apoptosis, but also suppresses the induction of replication-stress-induced DNA double-stranded breaks.

    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.

    A new class of disordered elements controls DNA replication through initiator self-assembly

    Matthew W Parker et al.
    DNA replication initiation proteins contain a disordered domain that impacts each stage of their function, from chromatin recruitment and initiator co-assembly to the subsequent displacement of the factors from chromatin.

    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.
