title: [A comparison of effects of agents stabilizing or destroying the water structure on conformational changes of a DNA molecule in solutions exposed to gamma-irradiation].
abstract: It was shown that gamma-irradiation of water-ethanol and water-n-propanol solutions of DNA with doses of 10-30 Gy leads to a fall of the specific volume of the macromolecule upon the cooperative transition at a critical concentration of alcohol in solution at which the destroying of water structure by a nonelectrolyte occurs.
