Query: Bending elasticity of macromolecules: analytic predictions from the
  wormlike chain model   We present a study of the bend angle distribution of semiflexible polymers of
short and intermediate lengths within the wormlike chain model. This enables us
to calculate the elastic response of a stiff molecule to a bending moment. Our
results go beyond the Hookean regime and explore the nonlinear elastic
behaviour of a single molecule. We present analytical formulae for the bend
angle distribution and for the moment-angle relation. Our analytical study is
compared against numerical Monte Carlo simulations. The functional forms
derived here can be applied to fluorescence microscopic studies on actin and
DNA. Our results are relevant to recent studies in "kinks" and cyclization in
short and intermediate length DNA strands.
