The term "step" refers to the curve obtained by means of dc polarography, while the ar polarographir curve is called a "wave" according to Breyer and B a u ~. ~4
In a continuing study of the denaturation of DNA as brought about by Cu(I1) ions, results are presented for the dependence of T , and T (the terminal relaxation time) on ionic strength, pH, reactant concentrations, and temperature. Maximum stability of the double helix, as reflected by the longest r
We show that denatured DNA from Tetrahymena mitochondria or phage TT, partially renatures during centrifugation in NaI equilibrium density gradients. This makes these gradients unsuitable for the analysis of single-stranded complementary nucleic acids, especially if their complexity and mole percent
The one-dimensional Ising model, with nearest-neighbor correlations only, used earlier in equilibrium studies of melting of DNA is extended to study the relaxation kinetics of copolymeric synthetic DXA near the melting temperature. An exponential kinetics, in agreement with the observations, has bee
