Superspiral structure of DNA
The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.In the past ten years, Chemical Custom synthesis Defeated many competitors, courageously advanced in the struggle, and polished many good products for customers. 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.
