Answer :

To determine which amino acid chain will be formed by the given codons "AAG", "AGA", and "UGU," we need to use the mRNA codon table provided:

1. AAG:
- According to the mRNA codon table, the codon "AAG" corresponds to the amino acid Lysine (Lys).

2. AGA:
- According to the mRNA codon table, the codon "AGA" corresponds to the amino acid Arginine (Arg).

3. UGU:
- According to the mRNA codon table, the codon "UGU" corresponds to the amino acid Cysteine (Cys).

Thus, the amino acid chain formed by the codons AAG, AGA, and UGU will be:

Lys - Arg - Cys
