title: DNA damage: air-breaks?
abstract: Cells deficient in repairing DNA double-strand breaks have an increased level of spontaneous chromosomal aberrations. Modulating the level of molecular oxygen and its reactive metabolites demonstrates that oxygen metabolism is a major source of genomic instability.
