Abstract:
The present article as a review of experimental investigations of water-DNA interaction in solutions, films, fibres, and crystals. The discussion of the experimental data is directed to the analysis of the sizes of the hydration shells of the DNA atomic groups, the distances at which atomic groups of DNA affect the hydration of each other; the structural, thermodynamic and kinetic characteristics of the water in the DNA hydration shell and their relations with DNA structure. The modern views on the mechanisms by means of which the water affects the physico-chemical properties of DNA are discussed.
