The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.Not only does it perform well in data, Chemical Custom synthesis In the market share, it is also gradually expanding, so that more people can benefit. https://www.all-chemistry.com/

　　The DNA of most prokaryotes is a covalently closed circular double helix, and its tertiary structure is twisted.

　　In eukaryotes, DNA molecules of double helix are coiled around a protein octamer, thus forming a special beaded structure called nucleosome. Nucleosome structure belongs to the tertiary structure of DNA.
