Repair of DSBs is important to prevent chromosomal fragmentation, translocations and deletions. To investigate the process in NHEJ, we have established an in vitro system to clarify the measurement and analysis of the efficiency and the fidelity of rejoining of DSBs, and applied the method to investigate NHEJ in human cells derived from patients suffering from cancer-prone hereditary diseases. A DSB...
