Question
- A. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must interpret diagrams of DNA structure without needing to reproduce them.
- B. Scale confusion: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing DNA structure (biology only).
- C. Process confusion: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on interpret diagrams of DNA structure without needing to reproduce them.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA structure (biology only).
Answer
The correct option is Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must interpret diagrams of DNA structure without needing to reproduce them.. 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 Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must interpret diagrams of DNA structure without needing to reproduce them.. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must interpret diagrams of DNA structure without needing to reproduce them. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must interpret diagrams of DNA structure without needing to reproduce them, so the answer must stay inside DNA structure (biology only). The alternative options are wrong because they either calling a gene a whole chromosome., explaining protein coding without naming the gene as the relevant section of dna., or drift away from when asking about genes, test a section of dna, protein coding, alleles, or inherited characteristics..
Common mistake
Misinterpreting DNA Diagrams
Students often struggle to accurately interpret the components of DNA diagrams, confusing the roles of bases, sugars, and phosphates.
Focus on understanding the structure of DNA, specifically how the sugar and phosphate backbone supports the base pairs, and practice interpreting various diagrams to reinforce this knowledge.
