Question
- A. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches DNA and the genome because students must define the genome as the entire genetic material of an organism.
- B. Reversed cause: Treating DNA as if it always means one gene. This would blur DNA vs genes instead of testing DNA and the genome.
- C. Missing link: Calling a gene a whole chromosome. This misses the objective focus on define the genome as the entire genetic material of an organism.
- D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA and the genome.
Answer
The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches DNA and the genome because students must define the genome as the entire genetic material of an organism.. 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 Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches DNA and the genome because students must define the genome as the entire genetic material of an organism.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches DNA and the genome because students must define the genome as the entire genetic material of an organism. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must define the genome as the entire genetic material of an organism, so the answer must stay inside DNA and the genome. The alternative options are wrong because they either treating dna as if it always means one gene., calling a gene a whole chromosome., or drift away from when asking about dna, test molecular structure, base sequence, nucleotides, or genetic information storage..
Common mistake
Confusing genome with a single gene
Students often think the genome is just one gene or a small part of DNA, rather than the complete set of genetic material in an organism.
Explain that the genome is the entire collection of DNA in all chromosomes, encompassing every gene and non‑coding sequence, and that it represents the full genetic blueprint of the organism.
