DNA is sometimes referred to as the blue print of the cell's information because it is the store house in which all genetic information necessary for the cell's survival and reproduction is kept.
Without DNA, there cannot be any continuation of life and no new generation of organisms. All living cells and organisms are essentially made up of protein in different forms. Apart from water, proteins are the most abundant molecules in the cell and body where they serves as the major structural component and are essential for growth and maintenance. Information for all these proteins is found in DNA. Without DNA, there can be no protein hence no life.
