## Synopsis The thermal denaturation method was employed to study the effect of Ca2+ and Mn2+ ions on the DNA helix-coil transition parameters at Na+ concentrations of 10-3-10-1M. A t low ion concentrations, thermal stability increases, the melting range passes through a maximum, and the denaturat
## Abstract The thermodynamics of the DNA helixβcoil transition is studied, starting from the thermodynamical potential difference between the states helix and coil; this potential difference is understood as the difference in free energies. With only three parameters obtained from experimental dat
## Abstract The helixβcoil phase transition of DNA is studied through a model equivalent to the one used in the theory of superconductivity. A distribution function for the excitations analogous to the usual Fermi function is obtained which depends on the parameter __T__~__0__~, the maximum tempera
