A nucleotide is composed of three components: a nitrogenous base, a phosphate group, and a pentose sugar. The nitrogenous base can be one of four types: adenine, guanine, cytosine, or thymine (in DNA) or uracil (in RNA). The phosphate group and pentose sugar (either deoxyribose in DNA or ribose in RNA) make up the backbone of the nucleotide molecule. Nucleotides are the building blocks of nucleic acids, including DNA and RNA.
