Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that DNA is contained in structures called chromosomes.
- B. Common misconception: Explaining protein coding without naming the gene as the relevant section of DNA. This would blur DNA vs genes instead of testing DNA and the genome.
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on explain that DNA is contained in structures called chromosomes.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA and the genome.
Answer
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that DNA is contained in structures called chromosomes.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in DNA and the genome.
Explanation
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that DNA is contained in structures called chromosomes.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA and the genome because students must explain that DNA is contained in structures called chromosomes. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must explain that DNA is contained in structures called chromosomes, so the answer must stay inside DNA and the genome. The alternative options are wrong because they either explaining protein coding without naming the gene as the relevant section of dna., treating dna as if it always means one gene., or drift away from do not use dna, gene, and chromosome as interchangeable answers..
Common mistake
Confusing DNA with chromosomes
Students often say DNA *is* a chromosome or that chromosomes are made of DNA, mixing up the two concepts.
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.
