DNA Unzipping Transition
Somendra M. Bhattacharjee
This review focuses on the force-induced unzipping transition of double-stranded DNA. It begins with a brief history of DNA melting, which emerged alongside the growth of the field…
Large bubble drives melting in circular DNA
Souradeep Sengupta, Somendra M. Bhattacharjee, Garima Mishra
We investigate the melting transition of non-supercoiled circular DNA of different lengths, employing Brownian dynamics simulation. In the absence of supercoiling, we find that mel…
A sheet-like structure in the proximity of compact DNA
Garima Mishra, Somendra M. Bhattacharjee
We determine the phase diagram of DNA with inter- and intra-strand native-pair interactions that mimic the compaction of DNA. We show that DNA takes an overall sheet-like structure…
Softening of DNA near Melting as Disappearance of an Emergent Property
Debjyoti Majumdar, Somendra M. Bhattacharjee
Near the melting transition the bending elastic constant, , an emergent property of double-stranded DNA (dsDNA), is shown not to follow the rod-like scaling for small length …
Bubble-bound state of triple-stranded DNA: Efimov Physics in DNA with repulsion
Jaya Maji, Flavio Seno, Antonio Trovato +1
The presence of a thermodynamic phase of a three-stranded DNA, namely, a mixed phase of bubbles of two bound strands and a single one, is established for large dimensions ($d\geq 5…
Rigidity of Melting DNA
Tanmoy Pal, Somendra M. Bhattacharjee
The temperature dependence of DNA flexibility is studied in the presence of stretching and unzipping forces. Two classes of models are considered. In one case the origin of elastic…
