Nucleotides are the organic molecules which serve as monomer units for the formation of nucleic acid polymers which are the deoxyribonucleic acid and the ribonucleic acid (RNA) and both are the essential biomolecules within the life on the Earth.
Nucleotides are building blocks of the nucleic acids. They are the molecules which are composed of three sub units which are:
Nitrogenous base which is also called as nucleobase
Five-carbon sugar which can be ribose or deoxyribose
At least one phosphate group which is attached to the sugar.
