Sensitivity Analysis for the Mechanical Properties of DNA Bundles

Figure 6

Bundle rigidities computed using several DNA models. (a) Bending and (b) torsional rigidities of the bundle. M1, M2, and M3 are continuum models where each DNA double helix is modeled as an isotropic cylinder. The helices are not connected in M1, continuously connected over the helices in M2, and discretely connected only at crossover positions in M3. B.M represents the beam model of the bundle (Figure 1). Shaded areas represent the experimentally measured rigidities.
