Abstract

Study on the interaction of DNA-specific ligands – classical intercalator acridine orange (AO) and groove binding compound Hoechst 33258 (H33258) with poly(rA)-poly(rU), being a model for double-stranded (ds-) RNA, has been carried out. The absorption and fluorescence spectra of the complexes of these ligands with ds-polynucleotide were obtained. It was revealed that the optic and fluorescent characteristics of the complexes of both ligands with ds-RNA are similar with those at the complex-formation with DNA.
