Statistical Mechanics of thermal denaturation of DNA oligomers
Navin Singh, Yashwant Singh
Double stranded DNA chain is known to have nontrivial elasticity. We study the effect of this elasticity on the denaturation profile of DNA oligomer by constraining one base pair a…
Force-induced desorption of a linear polymer chain adsorbed on an attractive surface
P. K. Mishra, Sanjay Kumar, Yashwant Singh
We consider a model of self-avoiding walk on a lattice with on-site repulsion and an attraction for every vertex of the walk visited on the surface to study force-induced desorptio…
Freezing Transitions in the fluid of long elongated molecules
Pankaj Mishra, Jokhan Ram, Yashwant Singh
We have used the density-functional theory to locate the freezing transitions and calculate the values of freezing parameters for a system of long elongated molecules which interac…
A simple model for the relative stabilities of DNA hairpin structure
Debaprasad Giri, Sanjay Kumar, Yashwant Singh
A model of self-avoiding walk with suitable constraints on self-attraction is developed to describe the conformational behaviour of a single stranded short DNA molecule that form h…
Adsorbed states of a long - flexible polymer chain
Yashwant Singh, Debaprasad Giri, Sanjay Kumar
A phase diagram for a surface-interacting long flexible polymer chain in a two-dimensional poor solvent where the possibility of collapse exists is determined using exact enumerati…
