A Scientist Makes Three Artificial MRNA Strands: (X) 5' AAAUUUAAAUUUAAAUUUAAAUUUAAA

question 11

Multiple Choice

A scientist makes three artificial mRNA strands: (x) 5' AAAUUUAAAUUUAAAUUUAAAUUUAAA 3'
(y) 5' UUUCCCUUUCCCUUUCCCUUUCCCUUU 3'
(z) 5' AUAUAUAUAUAUAUAUAUAUAUAUAU 3'
When he analyzes the polypeptides produced, he finds that:
X produces a polypeptide that is 50% phenylalanine and 50%lysine.y produces a polypeptide that is 50% phenylalanine and 50% proline.z produces a polypeptide that is 50% isoleucine and 50% tyrosine.Based on these results only, the best conclusion to make is that

• A)AUA codes for isoleucine
• B)AAA codes for phenylalanine
• C)AAA codes for lysine
• D)AAA codes for lysine and AUA codes for isoleucine
