Answer:
Stop Codon.
Explanation:
We need to study the codon UAA in the genetic code.
It is important to take into account the following information about genetic code:
-The First - start codon is AUG. Methionine is the only amino acid specified by just one codon.
-The stop codons may be three of those: UAA, UAG, and UGA. They encode no amino acid. The sequence stops.
According to this information. When coded by mRNA codon UAA. There is not aminoacid, because it is the stop codon.
Finally, we can conclude that codon UAA coded by the mRNA is Stop Codon.
