Quick explanation

Explain that DNA is contained in structures called chromosomes

  • This point belongs to Reproduction, especially DNA and the genome.
  • You need to be able to explain that DNA is contained in structures called chromosomes.
  • The key ideas to know are DNA and chromosome.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect DNA and the genome to exam-style questions, flashcards, and revision notes for Reproduction.

Quick student answer

How do you explain dNA is contained in structures called chromosomes?

Direct answer

In Biology, this page helps you answer questions about dNA is contained in structures called chromosomes within Reproduction. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are chromosome and DNA.

Key terms

  • chromosome: A thread‑like structure found in the nucleus of a cell that contains DNA and proteins, and which carries genetic information.
  • DNA: In DNA and the genome, DNA means the specific Unit 4.6 idea used to answer this objective: students must explain that DNA is contained in structures called chromosomes. Keep the term curriculum-specific by applying this boundary: DNA is the molecule; a gene is a functional section of that molecule. Do not use DNA as a vague inheritance word; link it to Reproduction and explain the exact role it plays in AQA GCSE Biology.

Common trap

Confusing DNA with chromosomes: Explain that DNA is the genetic material that is packaged into structures called chromosomes; chromosomes are the visible, thread‑like structures in the nucleus that contain many DNA molecules.
