1 Answer

Answer :

Nucleotides are compounds formed by nitrogen base , pentose sugar and phosphate. That is , one molecule of nitrogen-based base , one molecule of five-carbon sugars, and one molecule of inorganic phosphate is added to form a molecule called a nucleotide. The structural unit of nucleic acid is the nucleotide.
