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.
