Finally, abbreviations used for amino acid residues with more than one potential identity, and the termination codon are shown in red to complete the alphabet of single letter abbreviations. What is ...

Proteins are built from smaller units called amino acids, which are specified by three-nucleotide mRNA sequences called codons. Each codon represents a particular amino acid, and each codon is ...

Hence, the resulting products provided clues that the researchers could use to deduce potential codon–amino acid relationships. For example, when A and C were mixed with polynucleotide ...
