Before revision: We present a phenomenological dynamical model able to describe the stretching features of a lengthvs applied forceDNA curve. As concerning the chain, the model grounds on the discrete worm-like chain model with the elastic modifications, which properly describes the elongation features at low and intermediate forces.
