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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.
- 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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.
- 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 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 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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.. 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 recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. 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 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 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.
