Figure 6:
                    Stimulation of the Binding of C14-lysyl-tRNA to Ribosomes by Trinucleotides
                                                             (Khorana, 1965)

Which of the sequences AAG, AGA, GAA stands for lysine?
       Binding of C14-lysyl-tRNA to ribosomes in the presence of increasing amounts of the above trinucleotides. Greatest binding by AAA and AAG. Thus these two code for the amino acid lysine.
