What is DNA?

DNA stands for Deoxyribonucleic Acid. One way to think about DNA is that it is the blue-print for life. The DNA that is present in the vast majority of cells in a person’s body determines what eye color and hair color that the person will have, how tall the person will be and to some extent the person’s temperament, as just a few examples. Just like when you are building a house, you would have a blue-print to tell you how large the living room will be, for example. Our cells also have a blue-print, which is the DNA that gives each individual person their unique traits (barring identical twins).
