This table shows the 64 codons and the amino acid encoded by each.
Two of the three stop codons used in the Universal Genetic Code are reassigned to code for Glutamine (Q). Stop codon
reassignment is common in ciliated protozoa, with at least four
different nuclear genetic codes used within the group.
