Question
Describe the biological functions of nucleic acid compounds.

Answer

DNA is the chemical basis of heredity and may be regarded as the reserve of genatic information.
DNA is exclusively responsible for maintaining the identity of different species of organisms over millions of years.
DNA molecule is capable of self duplication during cell division and identical DNA strands are transferred to daughter cells.
Actually, the proteins are synthesized by various RNA molecules in the cell but the message for the synthesis of a particular protein is present in DNA.
