(C) In $1961$,Marshall $Nirenberg$ and Heinrich $Matthaei$ performed a landmark experiment to crack the genetic code. They used a synthetic poly-uracil $(poly-U)$ $RNA$ sequence in a cell-free system. They observed that this $poly-U$ sequence directed the synthesis of a polypeptide chain consisting entirely of the amino acid phenylalanine. Since the codon $UUU$ was the only repeating unit in the $poly-U$ sequence,they concluded that $UUU$ codes for phenylalanine. Thus,$UUU$ was the first codon to be deciphered.

The first codon discovered by $Nirenberg$ and $Matthaei$ was:
