WebA closed circular supercoiled DNA is relaxed by treatment with topoisomerase. No matter how much enzyme is used, or how long the experiment is run, the experimenter always … Weberties, and the closed circular, superhelical form is required in a number of genetic processes (1). We recently reported NMR experiments performed on supercoiled DNA, in which we compared the 31P relaxation properties of closed circular, nicked (kb)] plasmid DNA that incorporates the 2,800-bp human in-sulin gene (2).
WebRelaxed circular DNA consists of plasmid DNA that has been nicked and patched back up. This form should present as multiple bands or a small gradient of DNA bands. Depending … WebCircular DNA .
