Nucleic acids play a central role in biology and life in general: deoxyribonucleic acid (DNA) contains the genetic information. Damage in the DNA sequence can lead to mutagenesis and carcinogenesis. Often, damage in DNA is caused by radical reactions as a consequence of oxidative stress. Reductive as well as oxidative hole transfer chemistry through DNA is subject of wide interest because of its biological relevance and biotechnical application. One of the most used methods to study charge transfer through DNA is fluorescence spectroscopy. The intrinsic fluorescence of the naturally occurring nucleotide bases is almost absent. This drawback can be overcome by the use of non-natural nucleotide base analogs with optimized fluorescence properties. In this thesis, structural determination spectroscopy of a DNA duplex with PydU incorporated and of a control DNA hairpin at natural abundance is accomplished by NMR at natural abundance.
