Superspiral structure of DNA
The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.Hope for the future small molecules It can achieve rapid and stable development and serve social development and people’s needs well. 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.
