  • Sensitive yeast genetic system for identifying agents causing double-stranded DNA damage
    Patent number: 5352581
    Abstract: A sensitive, yeast-based genetic system for identifying agents causing double-strand DNA damage is described. The system comprises a yeast strain containing either chromosomes having divergent (homeologous) DNA sequences, a single nonhomologous chromosome or a single artificial chromosome with suitable genetic markers so that double-strand damage leading to the loss of such chromosome due to the inability to undergo recombinational repair with a homolog is detected.
