Question detail
Which option avoids the common misconception in this objective for Reproduction, DNA structure (biology only): students must state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.

Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA structure (biology only) because students must state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.
- 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 structure (biology only).
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA structure (biology only).
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 structure (biology only) because students must state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in DNA structure (biology only).
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 structure (biology only) because students must state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches DNA structure (biology only) because students must state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required, so the answer must stay inside DNA structure (biology only). 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 Required Knowledge
Students often believe they need to know detailed structures of mRNA, tRNA, amino acids, and proteins for the exam.
Focus on the fact that detailed knowledge of these structures is not required, as stated in the learning objective.
