  Stochastic reaction-diffusion processes may be presented in terms of
integrable quantum chains and can be used to describe various biological and
chemical systems. Exploiting the integrability of the models one finds in some
cases good agreement between experimental and exact theoretical data. This is
shown for the Rubinstein-Duke model for gel-electrophoresis of DNA, the
asymmetric exclusion process as a model for the kinetics of biopolymerization
and the coagulation-diffusion model for exciton dynamics on TMMC chains.
