Web8 Jun 2024 · The structure of DNA is called a double helix, which looks like a twisted staircase. The sugar and phosphate make up the backbone, while the nitrogen bases are found in the center and hold the two strands together. The nitrogen bases can only pair in a certain way: A pairing with T and C pairing with G. This is called base pairing. WebDNA backbone cleavage is accomplished by AP lyase activity from DNA glycosylases or DNA AP endonuclease activity Removal of the N-glycosidic bond by these glycosylases generates an apurinic/apyrmidinic (AP) or a-basic site.
