We analyze the stretching elasticity of a wormlike chain with a tension discontinuity resulting from a Hookean spring connecting its backbone to a fixed point. The elasticity of isolated semiflexible filaments has been the subject in a significant body of literature, primarily because of its relevance to the mechanics of biological matter. In real systems, however, these filaments are usually part of supramolecular structures involving cross-linkers or molecular motors, which cause tension…

This work analytically calculates the probability densities associated with the fluctuating tip and the corners of a grafted system of connected quadrilaterals and reveals that the force-extension relations depend on the contour length of the system, the bending stiffness, the geometrical angle and the number of the quadrillaterals, while the Poisson's ratio depends only on the ge graphically inclined angle.

The cross-over to the strongly bound state can be interpreted as a mechanism for force-stiffening which exceeds the capabilities of single-chain elasticity and thus available only to reversibly cross-linked polymers.

In vitro reconstitution of ‘functional modules’ of the cytoskeleton is now seen as a way of balancing the mutually conflicting demands for simplicity, which is required for systematic and quantitative studies, and for a sufficient degree of complexity that allows a faithful representation of biological functions.

The mechanical interactions between mouse brain myosin V and rabbit skeletal F-actin are measured and it is proposed that the 36-nm steps of the double-headed motor are a combination of the working stroke of the bound head and a biased, thermally driven diffusive movement of the free head onto the next target zone.
