DNA and RNA Structure

Question 12 • First Semester Biology

What is the role of RNA?

Answer

to provide the original blueprint for protein production

to move information from the ribosomes to the nucleus for protein synthesis

to break down proteins into amino acid monomers

to move information from the nucleus to the ribosomes for protein synthesis

Explanation

RNA, especially messenger RNA (mRNA), carries genetic instructions copied from DNA in the nucleus to ribosomes. Ribosomes use those instructions to assemble proteins. DNA provides the original blueprint, so RNA moves the information rather than serving as that blueprint.
