Thermal denaturation of A-DNA
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 only form that is stable in an aqueous environment. Other forms, however, can teach us much about DNA. They have the same nucleotide base pairs for ‘bui...
متن کاملThermal denaturation of a helicoidal DNA model.
We study the static and dynamical properties of DNA in the vicinity of its melting transition, i.e., the separation of the two strands upon heating. The investigation is based on a simple mechanical model which includes the helicoidal geometry of the molecule and allows an exact numerical evaluation of its thermodynamical properties. Dynamical simulations of long-enough molecular segments allow...
متن کاملThermal Denaturation Equilibria of Tmv Coat Proteins
Thermal denaturation of RNA free coat proteins of tobacco mosaic virus (TMV) was studied for wildtype TMV (vulgare) and the temperature-sensitive mutant, Ni 118. The ability to form soluble aggregates as well as the optical properties (ORD, UV-difference spectra), and the sedimen tation behavior were used as criteria for the native state. At pH 7.5 , 7 = 0 .0 2 denaturation is reversible for b...
متن کاملThermal denaturation of DNA studied with neutron scattering.
The melting transition of DNA, whereby the strands of the double-helix structure completely separate at a certain temperature, has been characterized using neutron scattering. A Bragg peak from B-form fiber DNA has been measured as a function of temperature, and its widths and integrated intensities have been interpreted using the Peyrard-Bishop-Dauxois model with only one free parameter. The e...
متن کاملMechanical denaturation of DNA: existence of a low temperature denaturation
Recent theoretical predictions on DNA mechanical separation induced by pulling forces are numerically tested within a model in which self-avoidance for DNA strands is fully taken into account. DNA strands are described by interacting pairs of self avoiding walks (SAW) which are pulled apart by a force applied at the two extremities. The whole phase diagram is spanned by extensive Monte Carlo (M...
