1. Triplets that appear in the 1st reading frame and that are of the type RNY; a) The extended RNA code type I: 2. Triplets that appear in the 2nd reading frame of the RNY pattern and are of the type NYR; 3. Triplets that appear in the 3rd reading frame of the RNY pattern and are of the type YRN; 4. Triplets that do not appear in the extended RNA code type I (RRR or YYY); 5. Amino acids that do not belong to the extended RNA code type I; b) The extended RNA code type II: 6. Triplets that underwent a mutation in their 1st nucleotide position (YRY and YYY); 7. Triplets that underwent a mutation in their 3rd nucleotide position (RRR and RYR); 8. Triplets that do not appear in the extended RNA code type II (YYR and YRR). 9. Amino acids that do not belong to the extended RNA code type II.
