Electron addition to DNA–thymine vs cytosine radical anion?
Abstract
Comparison of the EPR spectra of a self-complementary oligonucleotide (24-mer) containing either thymidine or [6-2H1]thymidine residues following irradiation in frozen aqueous LiCl matrices allows the unambiguous analysis of thte radical anion population in model DNA systems; these studies show that C˙–(1): T˙–(2) is 85 : 15.
