Abstract : The Research Objective was to ascertain the physical parameters of DNA in saline solution for which resonant absorption of microwave illumination could be expected; to extend the parameter evaluation so that microwave absorption studies can become a tool for examining the interaction between DNA polymer and its solvent. DNA polymer in aqueous solution responds to microwave illumination. Depending on the nature of the solvent in the immediate vicinity of the molecule, long lived resonances may be excited. These resonances correspond to standing compressional waves of varying frequencies on the polymer chain. Account is taken of the dielectric properties of the aqueous medium, ionic conductivity arising from dissolved salt, condensation of the salt ions near the polymer, and the variation of all the parameters with temperature and ion concentration.
