Nucleotides are the macromolecular building blocks of DNA and RNA. ... The nitrogenous base that makes up the nucleotide can vary between adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA). Furthermore, the sugar can also vary between deoxyribose in DNA and ribose in RNA.

Each RNA nucleotide consists of three parts: a sugar, a phosphate group, and a nitrogen-containing base. The four RNA bases are adenine, uracil, guanine, and cytosine—often referred to as A, U, G, and C. RNA shares three bases in common with DNA: adenine, guanine, and cytosine. Instead of uracil, DNA contains thymine.
