Bubble generation in a twisted and bent DNA-like model
arXiv:nlin/0408061 · doi:10.1103/PhysRevE.70.036609
Abstract
The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investigated in two different configurations. Using random normally distributed initial conditions to simulate thermal fluctuations, a relationship between bubble generation, twist and curvature is established. An analytical approach supports the numerical results.
