The impact of damping effect and external forces to the DNA breathing isinvestigated within the Peyrard-Bishop model. In in the continuum limit, thedynamics of the breathing of DNA is described by the forced-damped nonlinearSchrodinger equation and studied by means of variational method. The analyticalsolutions are obtained for special cases. It is shown that the breatherpropagation is decelerated in the presence of damping factor without theexternal force, while the envelope velocity and the amplitude increasesignificantly with the presence of external force. It is particularly foundthat the higher harmonic terms are enhanced when the periodic force is applied.It is finally argued that the external force accelerates the DNA breathing.
