Let's say there's a disaster that sends humanity back to the Stone Age. Can our knowledge and history survive? The printed page will decompose. Hard drive storage will deteriorate. Even stones will eventually crumble. But we might have something inside us that can outlast these physical limitations: deoxyribonucleic acid. DNA already stores our biological information. From eye color to skin tone, it programs our entire bodies. DNA is made of four organic bases: adenine, guanine, cytosine, and thymine, or A, G, C, and T. The specific sequence of these bases into groups of three, known as codons, gives our cells instructions to make each of the proteins in our bodies. But this code can be used for other things, too, like secret messages. ...
