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
Raman spectra have been recorded for poly (dG-dT) . poly(dAdC) and poly (dA-dT) . poly(dA-dT) in low salt and at high concentrations of CsF. Poly(dGdT)poly (dAdC) shows no change in the 682-cm-I guanine mode, demonstrating the absence of the Zstructure at high salt. The 790-cm-I phosphodiester symm
