Which mRNA codes for the following polypeptide?

met arg ser leu glu

A.	3'-AUGCGUAGCUUGGAGUGA-5'
B.	3'-AGUGAGGUUCGAUGCGUA-5' The sequence must be 5'-AUG for met, CGU for arg, AGC for ser, UUG for leu, and GAG for glu followed by a stop codon UGA. One sequence starts correctly but includes a stop codon in the third triplet (UAG).
C.	5'-AUGCGUAGCUUGGAGUGG-3'
D.	1'-AUGCGUAGCUUGGAGUGA-3'
E.	3'-AUGCGUAGCUUGGAGUGA-1'
