title: [Difference in DNA enthalpies in the helical and coiled states near 0 K].
abstract: On the basis of experimental data of DNA heat capacity in a wide range of temperatures the fundamental characteristics of DNA-H(0)0-the enthalpy of helix coil transition at 0(0)K were estimated. H(0)0 = 8.41 +/- 1.6 kJ/MBP. It was shown that a deviation from Nernst theorem (resulting from metastability of the system) was not obtained within the range of experimental error.
