FIG. 2.
(color online) Mobility versus extension. All simulations correspond to w = 4.6 nm and a = 1.38 nm. (a) Results for five different chain lengths for lp = 53 nm. The shaded region corresponds to the extensions seen in DNA experiments [8]. (b) Results for three different persistence lengths for L = 9:42 μm (Nb = 2048 beads). The dotted line is the scaling of eq. (4) and the dashed line shows the scaling of eq. (5). The solid lines are the approximation in eq. (6). The vertical lines are the values for the onset of the scaling 〈X〉/L ~ D–1 for the 53 nm chain (red, 〈X〉/L = 0.15) and the 23 nm chain (green, 〈X〉/L = 0.2).
