Title: Damaged DNA
Caption: Computer-generated model of nicked (damaged) DNA. Nicking involves the severing of a single strand of the DNA duplex. Both nicks and breaks are induced by UV light. Nicks are sealed by repair enzymes called ligases. The nick in this image is at the center, revealed by the absence of a (yellow) phosphorous atom.
