Which components participate in determining the order of amino acids during translation?

• A. mRNA codon sequence
• B. tRNA anticodons
• C. Ribosome
• D. All of the above

Answer: (D)

The order of amino acids during translation is set by the combination of the mRNA codon sequence, the tRNA anticodons that pair with those codons, and the ribosome that coordinates decoding and peptide bond formation. The mRNA carries the genetic code in codons, each specifying which amino acid should be added next. tRNA molecules deliver the appropriate amino acids, with anticodons that match the codons to ensure the correct amino acid is chosen for each step. The ribosome brings the mRNA and tRNA together, catalyzes the formation of peptide bonds, and moves along the mRNA to maintain the proper reading frame, ensuring the sequence of amino acids matches the codon order. Because all three components are essential for translating the code into a polypeptide, they collectively determine the final sequence of amino acids.
