`to` Nucleic acids are long chain polymers of nucleotides i.e poly nucleotides.
`to` Nucleic acids are constituted by pentose sugar, phosphoric acid, and nitrogenous hetero cyclic base (purine (or) pyrimidine).
Biological functions of nucleic acids :
`to` DNA is the chemical basis of heredity
`to` DNA is the reserve of genetic information
`to` DNA is capable of self duplication during cell division and indentical DNA strands are transfered to daughter cells
`to` RNA molecules are used in the protein synthesis in the cell
`to` The message for the synthesis of a protein in present in DNA
