Plot of radial distribution function (g(r)) versus radial distance for the filament (solid line) and hook (dotted line). The density of the filament is evenly dispersed over two peaks (domains D0, D1, and D2), whereas that of the hook is clustered primarily around a radial distance of 55 Å. Consequently, the filament has a more densely packed, rigid core than the hook, imparting it with a higher degree of stiffness.
