Photoreactivation and gene dosage in yeast.
The amount of photoreactivating enzyme in tetraploid cells of Saccharomyces cerevisiae and the ability of the cells to be photoreactivated after ultraviolet irradiation are directly proportional to the number of genes per cell involved in the synthesis of photoreactivating enzyme.
