lys - his - stop
his - arg - stop
phe - val - thr
lys - pro - arg

Explanation:

Step1: Find amino acid for AAG

In the codon table, for the codon AAG (first base A, second base A, third base G), it corresponds to Lys (Lysine).

Step2: Find amino acid for CAU

For the codon CAU (first base C, second base A, third base U), it corresponds to His (Histidine).

Step3: Find amino acid for UGA

For the codon UGA, it is a stop codon.

Answer:

Lys - His - STOP
