Relaxation dynamics of a single DNA molecule.

E Goshen1, W Z Zhao, G Carmon, S Rosen, R Granek, M Feingold.   

Abstract

The relaxation of a single DNA molecule is studied. The experimental system consists of optical tweezers and a micron-sized bead that is tethered to the bottom of the sample by a single double-stranded DNA molecule. The bead slows down the DNA relaxation from a strongly stretched configuration such that it is passing through stretched equilibrium states. This allows for a theoretical description of the relaxation trajectory, which is in good agreement with experiment.
