One ancestor for two codes viewed from the perspective of two complementary modes of tRNA aminoacylation
BACKGROUND: The genetic code is brought into action by 20 aminoacyl-tRNA synthetases. These enzymes are evenly divided into two classes (I and II) that recognize tRNAs from the minor and major groove sides of the acceptor stem, respectively. We have reported recently that: (1) ribozymic precursors o...
