Abstract: A model of self avoiding walks with suitable constraint has been developed tostudy the effect of temperature on a single stranded DNA ssDNA in theconstant force ensemble. Our exact calculations for small chains show that theextension reaction co-ordinate may increase or decrease with the temperaturedepending upon the applied force. The simple model developed here whichincorporates semi-microscopic details of base direction provide an explanationof the force induced transitions in ssDNA as observed in experiments.
