Superspiral structure of DNA

　　The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.In order to facilitate users to have a better experience, inhibitors Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. 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.
