DNA, deoxyribonucleic acid, is the miraculous double-helix molecule encoding the blueprints of all living things. It has been evolving for billions of years, yet its structure has only been known since 1953, when it was finally discovered by James Watson and Francis Crick. Today we can sequence entire genomes, revealing the basis of inherited disease and clues to our ancient heritage. This sculpture is a space-fill molecular model 4in (10cm) high, perfect for the desk or shelf of your favorite scientist or geek.
