What macromolecule results when tRNA delivers amino acids to the ribosome during translation?

• A. Nucleic acids
• B. Proteins
• C. Lipids
• D. Carbohydrates

Answer: (B)

During translation, tRNA brings specific amino acids to the ribosome and the ribosome links these amino acids together to form a growing polypeptide chain. This chain of amino acids folds into a functional protein, so the product of this process is a protein. The other options don’t fit because nucleic acids are DNA/RNA, lipids are fats, and carbohydrates are sugar polymers; none are built by stitching amino acids together at the ribosome.
