Notes:
Microcalorimetric heat capacity measurements on dilute and concentrated solutions and films of poly[d(A-T)·d(A-T)] in 2 M sodium chloride have been carried out. Values for enthalpy, entropy, and temperature of the helix-coil transition have been found to depend on the polymer concentration, and to have maxima near 20% (w/w) of polymer. The results are discussed in terms of polynucleotide hydration as one of the structure stabilizing factors.
