Nucleotides are the building blocks of nucleic acids. They are organic molecule made up of a nucleotide base, a five-carbon sugar and one phosphate group. Nucleotides make up the basic units of DNA and RNA molecules.
For example: Adenosine mono phosphate – AMP. Adenosine di phosphate-ADP. Adenosine tri phosphate-ATP. Nicotinamide adenine dinucleotide phosphate-NADP. Nicotinamide Adenine Dinucleotide Phosphate Hydrogen-NADPH. Deoxyribonucleic acid -DNA. Ribo nucleic acid-RNA.
