Question

print out the genetic code in the list of materials to answer this question.
a leafy sea dragons enzyme is being made in a cell.
which two codons represent the amino acid phenylalanine?
uua and uug
uuu and uuc
aau and ucc
auu and uua

Explanation:

To determine the codons for phenylalanine, we refer to the genetic code. The amino acid phenylalanine is encoded by the codons UUU and UUC. Let's analyze each option:

• Option 1 (UUA and UUG): These codons code for leucine, not phenylalanine.
• Option 2 (UUU and UUC): These are the correct codons for phenylalanine.
• Option 3 (AAU and UCC): AAU codes for asparagine, and UCC codes for serine, so this is incorrect.
• Option 4 (AUU and UUA): AUU codes for isoleucine, and UUA codes for leucine, so this is incorrect.

Answer:

B. UUU and UUC
