Question: 375

5. Translated to synthesize protein

A. DNA
B. tRNA
C. mRNA
D. rRNA
E. RNA polymerase

Correct Answer: C

Explanation:

C For this question, you really have to know the definition of translate and know which type of nucleic acid gets translated. Eliminate choice E first, because it is not a nucleic acid (it's an enzyme). You should also be able to eliminate choice A fairly easily, if you know that RNA, and not DNA, is the nucleic acid that is translated. Finally, you should know that mRNA (messenger RNA) is the nucleic acid that is read (translated) to synthesize protein.
