Clues to tRNA Evolution from the Distribution of Class II tRNAs and Serine Codons in the Genetic Code
We have previously proposed that tRNA(Gly) was the first tRNA and glycine was the first amino acid incorporated into the genetic code. The next two amino acids incorporated would have been the other two small hydrophilic amino acids serine and aspartic acid, which occurred through the duplication of...
