To determine the amino acid chain formed by the given codons, we need to use the genetic code. Here are the codons and their corresponding amino acids:
- Gly (GGU, GGC, GGA, GGG)
- Lys (AAA, AAG)
- Val (GUU, GUC, GUA, GUG)
- Cys (UGU, UGC)
- Glu (GAA, GAG)
Using this information, we can decode the codons provided in each option:
A. Gly (GGU) + Lys (AAG) + Val (GUC) = Gly Lys Val
B. Gly (GGU) + Lys (AAG) + Cys (UGC) = Gly Lys Cys
C. Glu (GAA) + Lys (AAG) + Cys (UGC) = Glu Lys Cys
D. Glu (GAA) + Lys (AAG) + Val (GUC) = Glu Lys Val
Therefore, the correct answer is option D: Glu Lys Val.
