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 define a gene as a small section of DNA on a chromosome.
- 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 define a gene as a small section of DNA on a chromosome.
- 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 define a gene as a small section of DNA on a chromosome.. 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 define a gene as a small section of DNA on a chromosome.. 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 define a gene as a small section of DNA on a chromosome. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must define a gene as a small section of DNA on a chromosome, 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
Misunderstanding the Definition of a Gene
Students often confuse the definition of a gene with that of a chromosome, thinking they are the same.
Emphasize that a gene is a specific segment of DNA located on a chromosome, and clarify the distinction between the two terms.
