As a key molecule of life, Deoxyribo-Nucleic Acid (DNA) is the focus of numbers of
investigations with the help of biological, chemical and physical techniques. From a physical …

Fluctuations in viscosity within the cell nucleus have wide limits. When a DNA molecule
passes from the region of high viscosity values to the region of low values, open states …

The imaginary time path integral formalism is applied to a nonlinear Hamiltonian for a short
fragment of heterogeneous DNA with a stabilizing solvent interaction term. Torsional effects …

The tethered particle motion (TPM) technique informs about conformational changes of DNA
molecules, eg upon looping or interaction with proteins, by tracking the Brownian motion of a …

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 …

The thermodynamical properties of heterogeneous DNA sequences are computed by path-
integral techniques applied to a nonlinear model Hamiltonian. The base pairs relative …

Statistical DNA models available in the literature are often effective models where the base-
pair state only (unbroken or broken) is considered. Because of a decrease by a factor of 30 …

Multistep denaturation in a short circular DNA molecule is analyzed by a mesoscopic
Hamiltonian model which accounts for the helicoidal geometry. Computation of melting …

By exploring a recent model in which DNA bending elasticity, described by the wormlike
chain model, is coupled to basepair denaturation, we demonstrate that small denaturation …

The closure of long equilibrated denaturation bubbles in DNA is studied using Brownian
dynamics simulations. A minimal mesoscopic model is used where the double helix is made …
