WebEach nucleotide consists of a phosphate group, a nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G)—and deoxyribose. DNA's sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring. Four carbons plus an oxygen are part of the five-sided ring.

WebA phosphate group attached to the 5′-end permits ligation of two nucleotides, i.e., the covalent binding of a 5′-phosphate to the 3′-hydroxyl group of another nucleotide, to form a phosphodiester bond. Removal of the 5′-phosphate prevents ligation. WebThey state that nucleotides contain phosphate groups, which are negatively charged clusters of one phosphorus atom bonded to four oxygen atoms and a hydrogen atom. Next, Pauling and Corey state that nucleotides also contain a sugar, a ring-shaped molecule containing carbon, hydrogen, and oxygen.
