DNA is a complex biomolecule which is embedded in the cells of all living organisms. DNA consists of two intertwined chains of simpler molecules. The arrangement of these units serves as a blueprint or recipe for the structure and internal activity of plants, animals, and people. Life is incredibly complex, and much guiding information is needed. Just one gram of DNA holds as much information as one trillion compact discs. Obviously, such computer storage capacity lies far beyond our technology.
