The excision of pyrimidine dimers from DNA of ultraviolet irradiated yeast

  • 215 Accesses

  • 105 Citations


It is shown that pyrimidine dimers formed by ultraviolet light in the DNA of haploid Saccharomyces cerevisae are removed under the influence of photoreactivating light and also in the dark under growth conditions. The integrity of the rad 1 locus is necessary for the dark-removal of dimers.
