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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.
- 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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.
- 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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.. 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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules, 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
Misunderstanding Protein Synthesis
Students often confuse the roles of ribosomes and the process of protein synthesis, thinking that ribosomes synthesize proteins directly rather than serving as the site where the process occurs.
Clarify that ribosomes are the cellular structures where protein synthesis takes place, using mRNA as a template and tRNA to bring amino acids, rather than thinking of ribosomes as the entities that create proteins themselves.
