DNA ligase

DNA ligases splint together strands of DNA by ligating (bonding) the 3'-OH and 5'-phosphate terminals of DNA. There are four DNA ligases in mammals: I-IV.

DNA ligases function in both DNA repair and replication, and are employed as research tools in recombination experiments.

double strand breaks

DNA double-strand breaks (DSBs) are potentially lethal, recombinogenic lesions that can be induced by exposure to external DNA damaging agents such as ionizing radiation or by endogenous events such as collapsed replication forks.
