AI overview
A nucleotide is a molecule made up of three parts: a five-carbon sugar, a nitrogenous base, and a phosphate group. Nucleotides are the basic building blocks of DNA and other important molecules in living cells.

Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.
