## Synopsis Systematic experimental data for the dependence of melting range width AT for phage T2 and calf thymus DNA's on sodium ion concentration was obtained. A mathematical description of helix-coil transition was given for the case of DNA with a block sequence of nucleotides (such as calf th
The magnitude and uniformity of the torsion elastic constant (a) of linear and supercoiled pBR322 DNAs are measured in 3 mM TI+, as a function of added chloroquine/basepair ratio (chl/bp) by studying the fluorescence polarization anisotropy of intercalated ethidium dye. The time-resolved FPA is meas
