Figure 8

Average thermodynamic potentials versus temperature derived from DNA unzipping experiments. (a) Basepair free energy and comparison with UO (4) and HU (10) predictions at 1 M NaCl, pH 7.0. The orange squares show the experimental results calculated by fitting the elastic parameters as described in Supporting Material. The gray (blue) dots are average UO (HU) values for the free energy/basepair. (b) Basepair entropy as a function of temperature under different salt conditions. (c) Basepair enthalpy under different salt conditions. For comparison with the theoretical predictions, we also show the average of the entropies/enthalpies of the 16 NN motifs under standard conditions (1 M NaCl, 298 K) for the UO (blue diamond) and HU (red diamond) predictions.
