The discovery of uracil and its pairing with adenine in RNA was a crucial milestone in understanding the genetic code and the central dogma of molecular biology. This knowledge laid the foundation for ...
The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine and guanine, are shown at the bottom. (Image: adapted from Wikimedia Commons, public domain) The ...
(Where DNA uses thymine, RNA uses uracil.) Two nucleotides together form a base pair; the sugars and phosphates form a ...
