Meiosis: early DNA double-strand breaks pave the way for inter-homolog repair
Abstract
During meiotic prophase, the repair of induced DNA double-strand breaks (DSBs) promotes interactions between homologous chromosomes (homologs). A study by Joshi et al. (2015) now highlights how the global DSB activity in a nucleus influences the choice between the homolog and the sister chromatid for DSB repair.
