AUG = Start or Met;UUU,UUC = Phe;UUA,UUG = Leu;UCU,UCC = Ser;CCU,CCC = Pro;ACU,ACC = Thr;UGA = Stop.
A)Thr-Phe-Thr
B)Phe-Leu-Ser-Ser-Thr-Pro
C)Met-Phe-Leu-Ser-Ser-Thr-Pro
D)Thr-Phe-Thr-Phe-Leu-Ser-Ser-Thr-Pro
E)Met-Phe-Leu-Ser-Ser

Quizplus · Accepted Answer

The mRNA transcript can be divided into three codons: AUG-UUU-UUA (encoding Met-Phe-Leu), UCC-UCC-ACU-CCU (encoding Ser-Ser-Thr-Pro), and UGA (Stop). Therefore, the polypeptide sequence would be Met-Phe-Leu-Ser-Ser-Thr-Pro, which is represented by choice C.
