Which process uses mRNA to assemble amino acids into a protein?

• A. Translation
• B. Transcription
• C. Replication
• D. Transduction

Answer: (A)

Translation is the process that uses mRNA to assemble amino acids into a protein. The ribosome reads the mRNA code three nucleotides at a time (codons), and each codon specifies which amino acid should be added next. Transfer RNA brings the matching amino acids and pairs its anticodon with the codon on the mRNA, allowing the ribosome to form peptide bonds and link amino acids into a growing polypeptide chain. This continues until a stop codon signals the end. Transcription, on the other hand, makes an RNA copy from DNA; replication duplicates DNA; and transduction involves transferring genetic material, not building proteins from mRNA.
