Reproduction

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 state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.
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 state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.
D. Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA structure (biology only).

Answer

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 state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.. 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 state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required. is correct because DNA is the molecule; a gene is a functional section of that molecule. 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 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 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.
