A short segment of an mRNA molecule is shown below. The polypeptide it codes for is also shown:
   5'-AUGGUGCUGAAG     :     methionine-valine-leucine-lysine
Assume that a mutation in the DNA occurs so that the fourth base (counting from the 5' end) of the messenger RNA now reads A rather than G. What sequence of amino acids will the mRNA now code for? (You do not need a copy of the genetic code to answer the question.)
A) methionine-valine-leucine-lysine
B) methionine-lysine-leucine-lysine
C) methionine-leucine-leucine-lysine
D) methionine-valine-methionine-lysine
E) methionine-methionine-leucine-lysine
