Calorimetric measurements of the transition enthalpy of DNA in aqueous urea solutions.

H Klump, W Burkart.   

Abstract

The helix-coil equilibrium of DNA is delicately affected by the nature of the solvent. In this investigation the helical secondary structure was destabilized by an increasing concentration of urea. We found a linear dependence of the transition enthalpy deltaH on the urea concentration for calf thymus DNA as well as for salmon sperm DNA.
