Question
- A. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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. Reversed cause: Treating DNA as if it always means one gene. This would blur DNA vs genes instead of testing DNA structure (biology only).
- C. Missing link: Calling a gene a whole chromosome. This misses the objective focus on recall (HT only) a simple description of protein synthesis on ribosomes using a template and carrier molecules.
- D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA structure (biology only).
Answer
The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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 Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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 is the molecule; a gene is a functional section of that molecule. 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 treating dna as if it always means one gene., calling a gene a whole chromosome., or drift away from when asking about dna, test molecular structure, base sequence, nucleotides, or genetic information storage..
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.
