The relaxation dynamics of semiflexible chain by introducing a time-dependent tension was studied. The semiflexible chain had one of its end attached to a large bead, and the other end was fixed and the initial relaxation of the chain was focused. The tension was solved by relating it to the Stokes drag acting on the dead, which, in turn, was result of the DNA contraction. The evolution of the end-to-end distance with no free parameter was obtained by using this tension which shows a good agreement with single molecule experiment on double stranded DNA.
