abstract：:Non-homologous end-joining (NHEJ) is the predominant pathway for the repair of DNA double-strand breaks (DSBs) in human cells. XRCC4 is indispensable to NHEJ and functions together with DNA ligase IV in the rejoining of broken DNA ends. Artemis is a nuclease required for trimming of some, but not all, types of broken ...
