In 1953, Watson and Crick presented their model for the DNA double helix, revealing the way genetic information is held in a cell. In the years since, DNA has proven to be a lively molecule that is looped, unwound, copied, repaired, edited, chemically modified, and more recently, engineered. A closer look at DNA's atomic structures (and its related cellular partners) has since revealed much more about the complex workings of this amazing molecule...
