Presentation transcript:

Plectonemic joints are joints in which one molecule is topologically wound around the other molecule. Plectonemic associations of DNA molecules can not be disrupted by deproteination, whereas paranemic joints can.paranemic joints Paranemic is a topological term for the joint that is made by wrapping one circle around another without cutting either circle. The two circles can always be pulled apart. Paranemic is distinguished from plectonemicplectonemic Paranemic Plectonemic
