A simple model for the relative stabilities of DNA hairpin structure
  A model of self-avoiding walk with suitable constraints on self-attraction is developed to describe the conformational behaviour of a single stranded short DNA molecule that form hairpin structure. Using exact enumeration method we calculate the properties associated with coil-hairpin transition. Our results are in qualitative agreement with the experiment.
