WebThe backbone: DNA structure has a backbone made of sugar and phosphate groups Deoxyribose – is a modified form of another sugar called ribose. Phosphate – acidic part of the molecule (balances the bases) The code: Nitrogen Base – DNA uses four kinds of nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Webthe sugar-phosphate backbone of a nucleic acid is directional In a strand of RNA or DNA, one end has an unlinked 5' phosphate while the other end has an unlinked 3' hydroxyl—meaning the groups are not bonded to another nucleotide. written in 5 --->3 direction primary structure of protein The order of the different nucleotides fucoxanthin-chlorophyll a-c binding protein
