Short explanation

Explain that a sequence of three bases codes for a particular amino acid.. 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.
