question 11

Multiple Choice

A short segment of an mRNA molecule is shown below.The polypeptide it codes for is also shown: 5'-AUGGUGCUGAAG : methionine-valine-leucine-lysine

• B)methionine-lysine-leucine-lysine
• C)methionine-leucine-leucine-lysine
• D)methionine-valine-methionine-lysine
• E)methionine-methionine-leucine-lysine
