Figure 7

(a) Frequency histograms of the step-size distributions of the sub-trajectories obtained from an experimental replicate of ColE1 DNA whose temporal positions are extracted from ALV (red and blue histograms for the first and second mode-set in –ALV zone, and green and shaded-green histograms for the first and second mode-set in +ALV zone) by setting the thresholds at ±2.2σALV. (b) The mean step sizes obtained from the experimental (red and blue circles for the first and second mode-set, respectively) and SrAr simulated (green circles and green squares for the second and first mode-set, respectively) sub-trajectories of ColE1 DNA at different threshold levels (0.1σALV – 2.2σALV). The mean step-sizes were determined by fitting the step-size distributions to equation (5). The dashed line shows the ALV threshold at which 10% of the data are collected. (c) The mean step sizes obtained from the experimental (red and blue circles for the first and second mode-set, respectively) and SrAr simulated (green circles and green squares for the second and first mode-set, respectively) sub-trajectories of the nanospheres at different threshold levels (0.1σALV−2.0σALV). Error bars in b,c correspond to the s.d.‘s of the step sizes at each threshold level obtained from 100 replicates.
