The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.With the expanding influence of the industry, Chemical Custom synthesis Our business is also constantly spreading, and the development of the market is also gradually advancing. 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.
