Figure 2.
(A) A schematic of the tRNA hierarchy. The amino acids are at the top level. At the bottom level one finds individual tRNA genes (isodecoders for a given anticodon). (B) Alignment of several isodecoders for the same anticodon (tRNAAspGTC). Some of the segments that are shared by various subsets of the listed isodecoders are shown shaded in different colors. (C) Alignment of isodecoders from different anticodons (such as tRNAAlaAGC and tRNACysGCA). As in (B), sequence segments shared by the listed isodecoders are shown shaded in different colors.
