Effects of Eye-phase in DNA unzipping
Debaprasad Giri, Sanjay Kumar
The onset of an "eye-phase" and its role during the DNA unzipping is studied when a force is applied to the interior of the chain. The directionality of the hydrogen bond introduce…
Force induced conformational transition in a system of interacting stiff polymer: Application to unfolding
Sanjay Kumar, Debaprasad Giri
We consider a stiff polymer chain in poor solvent and apply a force at one end of the chain. We find that by varying the stiffness parameter, polymer undergoes a transition from th…
Does changing the pulling direction give better insight into biomolecules?
Sanjay Kumar, Debaprasad Giri
Single molecule manipulation techniques reveal that the mechanical resistance of a protein depends on the direction of the applied force. Using a lattice model of polymers, we show…
Statistical mechanics of coil-hairpin transition in a single stranded DNA oligomer
Sanjay Kumar, Debaprasad Giri, Yashwant Singh
A model of self-avoiding walk with suitable constraints on self-attraction is developed to describe the conformational behavior of a short RNA or a single stranded DNA molecule tha…
