The influence of molecular confinement on the melting transition of oriented Na-DNA fibers submerged in poly(ethylene glycol) (PEG) solutions has been studied. The PEG solution exerts an osmotic pressure on the fibers which, in turn, is related to th

Thermodynamics of force-induced B-DNA melting: Single-strand discreteness matters
Autor: Nikos Theodorakopoulos
Publikováno v: Physical review. E. 99(3-1)
Overstretching of B-DNA is currently understood as force-induced melting. Depending on the geometry of the stretching experiment, the force threshold for the overstretching transition is around 65 or 110 pN. Although the mechanisms behind force-induc

Statistical Physics Of Dna: An Introduction To Melting, Unzipping And Flexibility Of The Double Helix
Autor: Nikos Theodorakopoulos
The stability of the DNA double helix is contingent on fine-tuning a number of physicochemical control parameters. Varying any one of them leads to separation of the two strands, in what constitutes a rare physical example of a thermodynamic phase tr

DNA is a flexible molecule, but the degree of its flexibility is subject to debate. The commonly-accepted persistence length of $l_p \approx 500\,$\AA\ is inconsistent with recent studies on short-chain DNA that show much greater flexibility but do n

We report model calculations on DNA single strands which describe the equilibrium dynamics and kinetics of hairpin formation and melting. Modeling is at the level of single bases. Strand rigidity is described in terms of simple polymer models; altern

The DNA molecule can take various conformational forms. Investigations focus mainly on the so-called ‘B-form’, schematically drawn in the famous paper by Watson and Crick [1]. This is the usual form of DNA in a biological environment and is the o

Low-temperature asymptotics of isotropic ferromagnetic chains at nonzero fields
Autor: Naoum C. Bacalis, Nikos Theodorakopoulos
Publikováno v: Physical Review B 55:1(Jan1997):52-55
We derive the leading-order asymptotics of classical one-dimensional isotropic ferromagnets near zero temperature in the context of two models with short-range interactions, namely the Heisenberg and the logarithmic chain. It is shown that the thermo

Biological organisms exist over a broad temperature range of � 15 � Ct oþ120 � C, where many molecular pro- cesses involving DNA depend on the nanoscale properties of the double helix. Here, we present results of extensive molecular dynamics s
