DNA is constantly being damaged by environmental agents such as ultraviolet light or certain compounds present in cigarette smoke. Cells unceasingly implement repair mechanisms for this DNA, which are of redoubtable efficacy. Scientists have for the first time managed to follow real-time the initial steps in one of these hitherto little known DNA repair systems.
