  We present an exact analysis of the intrinsic dynamics of two types of
biopolymers, described by the wormlike chain (WLC) and the wormlike rod chain
(WLRC) models, respectively. We map each model to a classical field theory for
an appropriate unit vector field defined on the space curve formed by the axis
of the biopolymer. Conformation dynamics and energy transport are shown to be
described, respectively, by the soliton-bearing Landau-Lifshitz equation and
the nonlinear Schr\"odinger equation. This enables us to identify the soliton
representing the ``conformon'' hypothesized in biopolymers.
