[Calorimetric study of the polyG-polyC complex].
Heat effects of polyG-polyC melting in neutral aqueous solutions have been measured using differential scanning microcalorimeter with an extended temperature range. The limiting value of melting enthalpy is 53 +/- 4 kJ per mole of base pairs and melting temperature dependence on the sodium concentration can be expressed by the empiric relation Tm = 13.2 log(Na+) + 420 K.
