| Abstract: | ![]()
DNA isolated from liver of healthy and tumor-bearing (sarcoma 45) rats was irradiated in water-salt solution with weak microwaves (64.5 GHz, 50 μW/cm2). The heat stability of DNA increased with irradiation time (a raise of 1.5°C in T m for “tumor” DNA after 90 min, without changes in ΔT), which may be associated with dehydration of the surrounding Na+ ions. |
