Figure 2. (a) The bending angle distributions p(θ, l) versus bending angle θ over 10 base steps for the central 14-bp segments of the DNAs with three sequences of AA-TT, AT-TA and GENE. The bending persistence lengths can be estimated by fitting the shown curves to equation (2). (b) The calculated bending persistence lengths from panel (a) compared with those values from [29, 42, 43, 67].
