"This Double Helix is a scientific model of B deoxyribonucleic acid, which is the most common form of DNA. DNA is a chemical carrier of our genes. It has an elegant geometric structure that allows it to store a massive amount of information. Every organism has its own DNA, and it is our DNA that makes each of us unique. Beads representing Phosphorus and Deoxyribose are 15 mm wide and multifaceted, and beads representing nitrogenous bases are oval and flat, 25 mmX20 mm."
