    Induction of homologous recombination between sequence repeats by the activation induced cytidine deaminase (AID) protein

    Jean-Marie Buerstedde et al.
    Intra- and intergenic deletions by repeat recombination broaden the mutagenic potential of the activation induced cytidine deaminase (AID) protein.

    Recombinational branch migration by the RadA/Sms paralog of RecA in Escherichia coli

    Deani L Cooper, Susan T Lovett
    The role of the bacterial protein RadA in homologous recombination – a DNA repair pathway vital to all cells – is defined.

    The kinetochore prevents centromere-proximal crossover recombination during meiosis

    Nadine Vincenten et al.
    The meiotic DNA recombination landscape is locally influenced by the kinetochore to minimize potentially deleterious pericentromeric crossover recombination.

    Recombination occurs within minutes of replication blockage by RTS1 producing restarted forks that are prone to collapse

    Michael O Nguyen et al.
    Homologous recombination is the default response to replication impedance by the RTS1 barrier, leading to restarted replication forks that suffer frequent collapse, triggering further rounds of recombination downstream of the barrier.

    Distinct roles for S. cerevisiae H2A copies in recombination and repeat stability, with a role for H2A.1 threonine 126

    Nealia CM House et al.
    Despite differing by only one amino acid in the C-terminal tail, copy 1 of yeast histone 2A has a repair-specific role not shared by copy 2.

    A curative combination cancer therapy achieves high fractional cell killing through low cross-resistance and drug additivity

    Adam C Palmer et al.
    Drugs in a curative chemotherapy regimen are independently effective and resisted by different mechanisms, so cancer cells have little chance of surviving all drugs, and this benefit occurs without synergistic interactions.

    TRF1 averts chromatin remodelling, recombination and replication dependent-break induced replication at mouse telomeres

    Rosa Maria Porreca et al.
    TRF1 suppresses replication fork stalling, which triggers break induced replication at telomeres associated with DNA damage response, alteration in the telomere chromatin environment, and re-localisation of telomeres to PML bodies.

    Structural snapshots of Xer recombination reveal activation by synaptic complex remodeling and DNA bending

    Aleksandra Bebel et al.
    DNA-bound crystal structures of an essential Xer site-specific recombinase from the bacterium Helicobacter pylori reveal how large conformational changes initiate the untangling of chromosomes upon cell division.

    Evolution of asymmetric gamete signaling and suppressed recombination at the mating type locus

    Zena Hadjivasiliou, Andrew Pomiankowski
    Selection for asymmetric signalling between gametes explains the very origins of sexual asymmetry as seen in mating-types with morphologically similar but self-incompatible gametes.

    Factors affecting template switch recombination associated with restarted DNA replication

    Manisha Jalan et al.
    Genomic deletions and gene conversions, caused by template switching associated with restarted DNA replication, are detected downstream of a collapsed replication fork and are suppressed by several conserved DNA helicases.
