The human body contains 100 trillion cells. Within each cell is a nucleus. Within each nucleus is a double copy of the human genome. Each genome contains 3.1 billion letters of genetic code, enough if transcribed to fill a library of five thousand books. Each cell, in other words, contains a blueprint of the entire body of which it is a part. The cumulative force of these scientific discoveries is nothing short of wondrous.
