RNA codewords and protein synthesis, 8. Nucleotide sequences of synonym codons for arginine, valine, cysteine, and alanine.

Abstract
Eleven trinucleotides were used as templates to direct the binding of Cl4-AA-sRNA to ribosomes. The results suggest that CpGpU and CpGpG serve as RNA codons for arginine, GpUpC, GpUpA, and GpUpG for valine, GpCpC, GpCpA, and GpCpG for alanine, and UpGpC6 for cysteine. CpUpA, ApUpA, and ApGpG had little detectable template activity for AA-sRNA. Possible nonsense codon sequences are discussed.
