    Mcm10 promotes rapid isomerization of CMG-DNA for replisome bypass of lagging strand DNA blocks

    Lance D Langston et al.
    Biochemical data demonstrate an unexpected and critical function for the enigmatic Mcm10 protein in helping the eukaryotic CMG helicase/replisome bypass roadblocks on the DNA that may also explain Mcm10 function at origins of replication.

    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.

    Ctf4 organizes sister replisomes and Pol α into a replication factory

    Zuanning Yuan et al.
    Eukaryotic replisomes are strongly connected together to replicate both sister DNAs produced from a bidirectional origin.

    Single-molecule visualization of fast polymerase turnover in the bacterial replisome

    Jacob S Lewis et al.
    The canonical model that the bacterial replisome tightly holds on to its polymerases is challenged by the visualization of rapid holoenzyme exchange, both in vitro and in vivo.

    TRAIP drives replisome disassembly and mitotic DNA repair synthesis at sites of incomplete DNA replication

    Remi Sonneville et al.
    The TRAIP ubiquitin ligase is required during mitosis to disassemble the replisome at sites of incomplete DNA replication, and activate the mitotic DNA repair pathway, thus preserving genome integrity.

    CMG helicase disassembly is controlled by replication fork DNA, replisome components and a ubiquitin threshold

    Tom D Deegan et al.
    Ubiquitylation of the CMG helicase is inhibited throughout the initiation and elongation phases of chromosome replication by the DNA structure of a replication fork.

    Reconstitution of a eukaryotic replisome reveals suppression mechanisms that define leading/lagging strand operation

    Roxana E Georgescu et al.
    The different polymerases at eukaryotic replication forks achieve their asymmetric placement on the leading and lagging strands through exclusion processes that prevent their function on the 'wrong' strand.

    Cohesion is established during DNA replication utilising chromosome associated cohesin rings as well as those loaded de novo onto nascent DNAs

    Madhusudhan Srinivasan et al.
    Sister chromatid cohesion is established during replication by two independent pathways operating in parallel, one converts chromosomal cohesin into cohesive structures while the other loads cohesin onto nascent DNAs.

    The interplay at the replisome mitigates the impact of oxidative damage on the genetic integrity of hyperthermophilic Archaea

    Tom Killelea et al.
    An investigation into 8-oxodeoxguanosine bypass by archaeal DNA polymerases.
