Abstract excerpt
Non-homologous end joining (NHEJ) is an error-prone but efficient primary repair pathway for DNA double-strand breaks (DSBs) during mitosis. A critical unresolved question is whether NHEJ acts as a backup when homologous recombination (HR) is impaired during meiosis. Here, we integrated biochemical, cytological, and genetic approaches to dissect the biological role of KU70/KU80, the core component of the NHEJ...
