| Abstract: | The polarographic method is used to show that the DNA preparations from the liver, spleen and tumour of leukemic rats in contrast to these preparations from the liver and spleen of the control ones possess a sharply marked electrochemical activity manifested by two peaks (peak I and peak II) in the region of the negative potential values. Peak I located in the region from--1.05 V to--1.30 V is determined by the activity of adenine and cytosine amine groups whereas peak II (from--1.45 V to--1.60 V) is caused by a protein component. |
