The START codon in eukaryotic mRNA translation is:
AUAA (one of three stop codons)
BUAG (one of three stop codons)
CAUG (codes for methionine, start)
DUGA (one of three stop codons)
Answer & Solution
Correct answer: C. AUG (codes for methionine, start)
AUG is the START codon and also codes for methionine. Translation always begins at the first AUG in proper context. Stop codons (UAA, UAG, UGA) terminate translation.
