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 interpret diagrams of DNA structure without needing to reproduce them.
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 interpret diagrams of DNA structure without needing to reproduce them.
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 interpret diagrams of DNA structure without needing to reproduce them.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA structure (biology only) because students must interpret diagrams of DNA structure without needing to reproduce them. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must interpret diagrams of DNA structure without needing to reproduce them, 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

Misinterpreting DNA Diagrams

Students often struggle to accurately interpret the components of DNA diagrams, confusing the roles of bases, sugars, and phosphates.

Focus on understanding the structure of DNA, specifically how the sugar and phosphate backbone supports the base pairs, and practice interpreting various diagrams to reinforce this knowledge.
