Superspiral structure of DNA

　　The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.As a representative of the industry, small molecules It is necessary to set a certain example for peers and lead the way in product quality. 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.
