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
