DNA

In 1953, James Watson and Francis Crick solved one of science's greatest enigmas: the molecule underlying all life. This fascinating guide to the double helix examines who we are, how we're wired, and how we repair ourselves. With information on "junk" DNA, how our genes evolved, heritability, the genetics of neuroscience, viruses, disease, and what happens when things go wrong, DNA takes a visual journey through the polymer chain.
