The use of the DNA-rubomycin complex resulted in appearance of one-thread breaks (OB) in DNA and markedly increased the number of the DNA OB determined immediately after irradiation. The DNA-rubomycin complex decreased the volume of the repaired OB and induced postreparation degradation of the one-bond DNA (oDNA) in the sarcoma 180 cells. The effect of the decrease in the molecular mass of the oDNA 6 hours after the irradiation to the level of the initial damage is probably in favour of the fact that degradation takes place in the areas of the repaired breaks. The data indicated that the viscosimetric method for the analysis of the OB in DNA may be promising in estimation of the efficacy of radiation and chemotherapy of solid tumors.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
