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 ...

Given that the TCG codon could efficiently instruct the ribosome to add the unconventional amino acid to a desired protein, the scientists reasoned that it might also add the new subunit to other ...
