In mRNA, AUG is the initiation and UAA, UAG and UGA are termination codons, therefore, the polypeptide cannot be synthesized beyond any of these triplets to the end of mRNA. Then which of the following will be translated completely?
AUG UGA UUA AAG AAA
AUG AUA UAG CCC UCA
AGU UCC AGA CUC UAA
AUG UAC AGU ACC UAG
Among the given options, stop codons are not present in between the mRNA transcript in option 4. Thus, it shows that there will not occur any termination between translation processes. Hence, the correct answer is option 4.
