[Modification of the DNA spatial structure when complexed with cisplatin]. / Modifikatsiia prostranstvennoi struktury DNK v komplekse s tsis-platinoi.

The experimental and theoretical analyses of the conformational transitions of DNA-cis-platinum complexes have been carried out. It is shown that at low concentrations of the ligand, the thermodynamic parameters of the helix-coil transition of the complexes are not the result of the local B-->A transition.
