Short explanation

Explain that each gene codes for a sequence of amino acids to make a specific protein.. Within Reproduction, this learning objective sits inside DNA and the genome for AQA Biology 8461. Focus on using ideas such as amino acids, gene, protein 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.

  • Gene‑Protein Link Misconception: Explain that a gene is a DNA segment that is first transcribed into mRNA, which is then translated by ribosomes into a polypeptide chain; the codon sequence in the mRNA determines the order of amino acids in the final protein.
