The action of ionizing radiation on dna in the presence of quinacrine part 2 esr study spin transfer in gamma irradiated lyophilized dna quinacrine complexes


, : The action of ionizing radiation on dna in the presence of quinacrine part 2 esr study spin transfer in gamma irradiated lyophilized dna quinacrine complexes. Radiation and Environmental Biophysics 13(2): 137-143

ESR spectra of different DNA-quinacrine complexes show as well at 77.degree. K as at 293.degree. K that there exists an electron transfer from the bases to quinacrine facilitated by the overlap of the .pi.-orbitals of the bases and the intercalated dye. The transfer range may extend over more than 25 or 50 nucleotides depending on the intercalation model considered.
