Evidential study of correlated events in biochemistry: Physicochemical mechanisms of nucleic acid hydration as revealed by factor analysis

Using a factor analysis technique, the experimental physicochemical data on the hydration of mononucleotides, several polynucleotides, their double‐helical complexes and natural DNAs were studied. The information about the factors determining the changes in physicochemical parameters vs the hydration was obtained. This work discusses a possible physical sense of the factors obtained and the expedience of using factor analysis to interpret the molecular‐biophysical experiments.
