Abstract excerpt
Chromosomal double-strand breaks (DSBs) in mammalian cells are usually repaired through either of two pathways: end-joining (EJ) or homologous recombination (HR). To clarify the relative contribution of each pathway and the ensuing genetic changes, we developed a system to trace the fate of DSBs that occur in an endogenous single-copy human gene. Lymphoblastoid cell lines TSCE5 and TSCER2 are heterozygous (+/-)...
