In 1953, Watson and Crick unlocked the structure of the DNA molecule and set into motion the modern study of genetics. This advance allowed our study of life to go beyond the so-called wet and dirty realm of biology, the complicated laboratory study of proteins, cells, organelles, ions, and lipids. The study of life could now be performed with more abstract methods of analysis. By discovering the basic structure of DNA, we had received our first glance into the informationbased realm locked inside the genetic code.
