Problem 13: mRNA polypeptide code

Correct!

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'
