Khorana performed experiments to decipher the codons that code for a particular amino acid. The results of these experiments using synthetic mRNAs and the corresponding polypeptide repeats that were generated are given in the table below. array |l|l| Synthetic mRNAs & Polypeptide(s) synthesized ( CAA )_n & ( Thr-Thr )_n and ( Asn-Asn )_n and ( Gln-Gln )_n ( UUC )_n & ( Ser-Ser )_n and ( Leu-Leu )_n and ( Phe-Phe )_n
