Superspiral structure of DNA

　　The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.Therefore, inhibitors Only then will more and more pump owners cheer for it and spread the value and function of the brand. 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.
