List three functions of nucleotides in a cell.

Explanation

i. Nucleotides are the building blocks of high molecular weight polymers (poly-nucleotides) called nucleic acids.
ii. Some of them act as energy carriers.
iii. In the sequence of three, they code for one amino acid in nucleic acids. Thus, some of them are carriers of hereditary information, i.e., genetic code.
iv. Some of them are co-enzymes.
