Promoted Misrejoining of X-ray Radiation-induced DNA Double-Strand Breaks in Novel DNA Ligase IV-Deficient Mouse Cells
{{output}}
DNA double-strand breaks (DSBs) are the most severe type of DNA damage in living organisms and are primarily repaired by two pathways: non-homologous end joining (NHEJ) and homologous recombination (HR). DNA ligase IV (LIG4) is essential for the final step of ... ...
