Short explanation

Explain that the order of bases controls the order of amino acids in a protein.. Within Reproduction, this learning objective sits inside DNA structure (biology only) for AQA Biology 8461. Focus on using ideas such as A, amino acid, bases, C accurately in your explanation. A strong response should define the core idea, describe the relevant biological process, and connect it back to the question wording instead of giving a vague definition. When revising, students should aim to explain the science clearly, include precise biological vocabulary, and show how the process or structure links to the wider topic rather than listing isolated facts.

Common mistakes

  • Base‑order misinterpretation: Explain that each codon (three bases) is read by the ribosome to specify a particular amino acid, so changing base order changes the amino‑acid order in the protein.
