WebDNA interstrand cross-links are complex lesions, highly toxic to cells, and difficult to repair because of the involvement of both strands of the DNA duplex. A single unrepaired inter-strand cross-link is sufficient to kill a cell, and multiple DNA repair pathways may be required to complete cross-link re-moval (1–7). WebDNA crosslinking agents exhibit a variety of DNA lesions, such as monoad-ducts, DNA-DNA interstrand or intrastrand crosslinks or DNA-protein cross-links. Agents that produce interstrand crosslinks (ICLs) exist naturally and are widely used in chemotherapy. Therefore, it is important to understand how the lesions induced by these agents are ... In genetics, crosslinking of DNA occurs when various exogenous or endogenous agents react with two nucleotides of DNA, forming a covalent linkage between them. This crosslink can occur within the same strand (intrastrand) or between opposite strands of double-stranded DNA (interstrand).
