Abstract:
The oxidation of DNA and RNA provides a facile approach for investigating the interaction of nucleic acids with proteins and oligonucleotides. In this article, we have outlined our understanding of the mechanism of DNA scission by 1,10-phenanthroline-copper(I) in the presence of hydrogen peroxide. We also discuss results obtained by using 1,10-phenanthroline-oligonucleotide conjugates in probing the size of the transcriptionally active open complex. Finally, we outline an effective method for converting DNA-binding proteins into site-specific modification agents by using 1,10-phenanthroline-copper(I).
