metadata.name: dc.description.abstract
metadata.value: DNA solutions in the presence of Ca2+, Mn2+ and Cu2+ ions were studied using FTIRspectroscopy
  and DNA melting analysis. An approach to the analysis of the IR-spectra of DNA
  was proposed. The approach is based on decomposition of complex bands in the region of carbonyl
  vibrations. It was shown that ions can interact with nitrogenous bases. It was also shown
  that the interaction of Ca2+ and Mn2+ ions occurs via water molecules, while Cu2+ ions bind
  the bases directly. The significant influence of Ca2+, Mn2+ and Cu2+ ions on the conformational
  stability of the DNA double helix has been demonstrated. It was shown that Ca2+ and Mn2+
  ions stabilize the DNA structure while Cu2+ ions serve to reduce its thermodynamic stability.
