WebThere are multiple pathways for repairing double strand breaks, mainly non-homologous end joining (NHEJ), homologous recombination (HR), and MMEJ. NHEJ directly joins both ends of the double strand break and is relatively accurate, although small (usually less than a few nucleotides) insertions or deletions sometimes occur.
