A nucleotide contains a base (adenine, thymine, guanine, or cytosine), sugar, and phosphoric acid.
Nucleotides are organic compounds that are composed of a base (one of the following four chemicals: adenine, thymine, guanine, and cytosine), in addition to a sugar molecule and a phosphoric acid molecule. They perform the function of monomeric units inside the nucleic acid polymers, which include ribonucleic acid and deoxyribonucleic acid. These two types of biomolecules are required for the survival of all kinds of life on Earth.
Nucleotides are required in order for metabolic processes and physiological functions to be carried out.
