## Abstract The helix–coil 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
Thermal denaturation of direct-mixed and reconstituted polylysine-DNA complexes in 2.5 X 10-4 M EDTA, pH 8.0 and various concentrations of NaCl has been studied. For both complexes, increasing ionic strength of the solution raises T,, the melting temperature of free base pairs. The linear dependence
## Abstract The effect of magnesium ions on the parameters of the DNA helix‐coil transition has been studied for the concentration range 10^−6^–10^−1^__M__ at the ionic strengths of 10^−3^__M__ Na^+^. Special attention has been given to the region of low ion concentrations and to the effect of poly
