Superspiral structure of DNA

　　The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.This shows that, inhibitors It has a strong development pulse and is an indispensable source of power for the development of the industry. 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.
