In molecular genetics, what is the universal start codon that initiates translation in eukaryotic protein synthesis?
Answer and explanation
Correct answer: B. AUG (coding for methionine)
- Step 1: AUG is the canonical initiation codon on mRNA, specifying the amino acid methionine in eukaryotes. Answer: AUG (coding for methionine). Why not the others: UAA, UAG, and UGA are termination (stop) codons that halt translation.
