X-ray induced degradation of DNA in radiosensitive mutants of Anacystis nidulans

Abstract

In irradiated Cyanophyceae (Anacystis nidulans) cells there occurs a process of DNA degeneration to acid-soluble products which is linked with protein synthesis and stimulated by caffeine and acriflavine. The degree of DNA degeneration increases with x-ray dose, is not very dependent on the composition of the incubation medium and is weakly linked with photosynthesis. In the cells of a radiation-resistant mutant the degree of DNA degeneration is slighter, and in the cells of radiosensitive mutants larger, than in ordinary cells. The role of DNA degradation in the radiation detruction of cells is discussed.
