The heats of the conformational conversion AH, of polyuridylic acid (polyu) in the presence of various cations were determined using a differential scanning microcalorimeter and an isothermal mixing calorimeter. The first method yields a value of AH, = Fi.2 kcal/mol of base pairs, the second one a v

## Synopsis Studies were made of the influence of hydrostatic pressure on the helix-coil transitions of poly(A + U) and poly(A + 2U). The results were analyzed by a thermodynamic treatment which emphasized the cooperative aspect of the transitions. The helix-to-coil volume changes were found to be
## Abstract The quasielastic light scattering of polyโLโlysine HBr in aqueous solutions has been examined over a variety of pH values where the polymer is in different conformations. Analysis of the spectra demonstrates that as the pH is lowered, the polymer changes from an extended anisotropic fro
Helix-coil transition curves are calculated for poly (dA).poly(dT) and poly (dA-dT). poly (dA-dT) using the integral equation approach of Goel and Montroll.6 The transitions are described by the loop entropy model with the exponent of the loop entropy factor, k, remaining an arbitrary constant. The
