DNA - Deoxyribonucleic acid

DNA - Deoxyribonucleic acid is the essential molecular structure controlling the development and functioning of almost all living organisms. It's responsible for carrying the genetic information that instructs cells to differientiate their functions in an organism. DNA molecules are found in all living cells and can be used to uniquely identify one organism from another, positively determine a long lost relative, or diagnose genetic diseases.

The lessons in this unit are designed to teach middle school and high school students about the basics of DNA, how it works, and how living organisms use DNA to grow and develop. The basic elements of life consisting of Carbon, Hydrogen, Nitrogen Oxygen, Phosphorus, and Sulfur are presented in Organic Compounds. Another lesson explores how humans derive energy from food molecules.
