with every codon consisting of three nucleotides (a specific type of organic molecule). To represent the different ...

Following this discovery, Nirenberg, Philip Leder, and Gobind Khorana identified the rest of the genetic code and fully described each three-letter codon and its corresponding amino acid.

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 ...
