Аннотация
In this work we study the effects of the solvent interaction on the
nonlinear dynamical structure of a DNA segment, by using a
time-independent perturbation approach. Considering a well-known set of
values for the spring constant (k) and the Morse (solvent) potential
parameters D-n and a(n) (f(s) and lambda(s)), we investigate the
denaturation temperature profiles of some DNA's thermodynamical
functions, such as the stretching of the hydrogen bonds, the specific
heat and the entropy. Besides a sharp thermal profile behavior of these
functions, we observe also that the DNA's melting temperature decreases
as the solvent potential increases. (C) 2014 Elsevier B.V. All rights
