S. cerevisiae of wild type diploid cells are characterized by a higher content of endogenous biologically active substances, which have radioprotective ability (amines and SOD [superoxide dismutase]) and a lower level of radiosensitizing substances (hydroperoxides of higher unsaturated fatty acids). With S. cerevisiae, bearing mutation rad 51, not all the components of the radioresistance background show this dependence. This indicates the presence of additional factors affecting radioresistance of these cells.
