Conformations of DNA Loop
Abstract: The formation and property of DNA loop are the basic problems of biophysics and soft matter physics. In present work, the conformational statistics is studied by Monte Carlo method based on the wormlike chain model. The priority conformational state for the different length of DNA loop is predicted and the force acting on the grafting point is also discussed.
