Experimental study of hysteresis phenomenon in the NaDNA Ibydralion-dehydration process

M. Ye, Tolstorukov, K. M. Virnik

Results of thi' experimental study of hysteresis phenomena in the NaDNA-water system carried out with using gravimetric technique are presented. Intervals of relative humidity where hysteresis is observed correlate with ones of stable DNA conformation existence. .Hysteresis phenomena reflect relationship between water sorption and conformationai transitions of biopolymer molecule.
