Quantitative analysis of contractile ring filaments with respect to the membrane surface. (A) Histogram of distances measured from the 20-nm segments (n = 5,032) of 740 filaments to the membrane. (B) Histogram of the distance measured between filament ends and the membrane. (C) Histogram of angles between the 20-nm segments and the membrane. (D) Scatterplot of the measured distance from the membrane as a function of the segment’s angle with respect to the membrane surface. The bin size is 1 nm in A and B, and 1° in C.
