  The temperature dependence of a charge mobility in a model DNA based on
Holstein Hamiltonian is calculated for 4 types of homogeneous sequences It has
turned out that upon rescaling all 4 types are quite similar. Two types of
rescaling, i.e. those for low and intermediate temperatures, are found. The
curves obtained are approximated on a logarithmic scale by cubic polynomials.
We believe that for model homogeneous biopolymers with parameters close to the
designed ones, one can assess the value of the charge mobility without carrying
out resource-intensive direct simulation, just by using a suitable
approximating function.
