Dna is shaped in the form of a double

WebThe histones form a disk-shaped complex called a nucleosome which has two complete turns of double-stranded DNA wrapped around it. These interactions are formed by positively charged amino acid residues in the histones making ionic bonds to the acidic sugar-phosphate backbone of the DNA, and thereby are largely independent of the base … WebA Double-Helix Structure. DNA has a double-helix structure, with sugar and phosphate on the outside of the helix, forming the sugar-phosphate backbone of the DNA. The nitrogenous bases are stacked in the interior in pairs, like the steps of a staircase; the pairs are bound to each other by hydrogen bonds. The two strands of the helix run in ...
