DESCRIPTION
DNA (Deoxyribonucleic Acid) is one of life's most important molecules. This is because DNA is responsible for storing all of the cell's information. It is a macromolecule made up of smaller subunits called nucleotides. There are four different nucleotides (A,T,C,G) and they pair together in a complementary manner. The structure of DNA is called a double helix.
