Which molecule serves as the final product of translation, forming the functional units of proteins?

• A. RNA
• B. Polypeptide
• C. Amino acid
• D. Protein

Answer: (B)

Translation builds a polypeptide chain by linking amino acids in the sequence specified by the mRNA. The ribosome coordinates this process, using tRNAs to bring the correct amino acids and forming peptide bonds between them. This polypeptide is the immediate product of translation, and it will later fold into a functional three-dimensional protein and may undergo post-translational modifications. RNA is the template used to guide the sequence, not the final output of translation; amino acids are the building blocks added during synthesis; a fully functional protein is produced only after proper folding and maturation.
