Reproduction

Question

A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. 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 contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing DNA structure (biology only).
C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on state (HT only) that detailed mRNA, tRNA, amino acid and protein structure is not required.
D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA structure (biology only).

Answer

Explanation

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. 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 contrast: DNA can contain many genes; a gene has a specific coding role. 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 can contain many genes; a gene has a specific coding role. 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 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 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.
