Introduction
1.DNA is the chemical basis of heredity and may be regarded as the reserve of genetic information. 2.DNA is exclusively responsible for maintaining the identity of different species of organisms over millions of years. 3.A DNA molecule is capable of self duplication during cell division and identical DNA strands are transferred to daughter cells. 4.DNA has a double helix structure 5.Another important function of nucleic acids is the protein synthesis in the cell. 6.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.
