Towards more realistic dynamical models for DNA secondary structure
  We propose a dynamical model for the secondary structure of DNA, which is based on the finite stacking enthalpies used in thermodynamics calculations. In this model, the two strands can separate and the bases are allowed to rotate perpendicular to the sequence axis. We show, through molecular dynamics simulations, that the model has the correct behaviour at the denaturation transition.
