Determination of the number of superhelical turns by the hyperchromicity of partially denatured covalently-closed DNA molecules.
A novel method of determining the number of superhelical turns of a covalently-closed plasmid DNA is described. It relies on the determination of the hyperchromicity, and hence the proportion of unstacked basepairs, of a partially heat-denatured sample which co-migrates during electrophoresis with n...
