Abstract:

Measurements have been made of the relative permittivity and conductivity of aqueous solutions of DNA in the 5 Hz-10 MHz frequency range. The types of DNA studied were plasmid and calf thymus. No evidence of resonance absorption or improved absorption was exhibited for either type of DNA in any part of the frequency range. The plasmid was studied at 20 C only, but measurements on the calf thymus DNA were extended down to -50 C. These measurements revealed the existence of a novel and hitherto unexpected dispersion region, the origin of which is due probably to the motion of ions through the water matrix adjacent to the DNA molecule. kt
