Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. In pea plants, height is determined by an allele for tallness (T) that is dominant over an allele for shortness (t). In DNA the base can be either one of the purines, adenine (A) or guanine (G), or one of the pyramidines, thymine (T) or cytosine (C). Knowledge of geometrical and physico-chemical properties of the sugar–phosphate backbone substantially contributes to the comprehension of the structural dynamics, function and evolution of nucleic acids. The sugar-phosphate backbone, as mentioned, is an important component of DNA’s double helix structure. A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar in DNA’s nucleotides is called deoxyribose—DNA is an abbreviation for deoxyribonucleic acid. These bases pair in very specific ways: A always pairs with T and G with C. Sugar-phosphate Backbone Function.

A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups. The pairing of the nitrogenous bases that are connected to the sugar-phosphate backbone play a key role in the ability of DNA to store and transfer genetic information. Complementary Base Nucleotide Base Pair Nucleoside Purine. The phosphate of one nucleotide is covalently bound (a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. Part 1 Activities.
