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).
