The microwave energy absorption in the 9-12 GHz range is investigated in chicken erythrocytes and E. coli DNA aqueous solutions, both for native macromolecules and those fragmented by ultrasound or by DNase. In all cases the characteristic absorption of DNA was not observed as well as for the E. coli DNA exposed to DNase for two hours. It is shown that the ion influence on the dielectric properties of DNA aqueous solutions must be taken into account carefully
