(Affiches/Poster) Liquids 2014 (9th Liquid Matter Conference) (Lisbon, PT), 2014-07-21 Ref HAL: hal-01948377_v1 Exporter : BibTex | endNote Résumé: The closure of long equilibrated denaturation bubbles in DNA is studied using Brownian dynamics simulations. A minimal mesoscopic model is used where the double helix is made of two interacting bead-spring freely rotating strands, with a nonzero torsional modulus in the duplex state. |
