Exam-style question
Try this first
Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Theory of evolution (biology only): students must describe how Darwin developed the theory of evolution by natural selection using observations, experimentation, discussion, geology and fossils.
- A.Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must describe how Darwin developed the theory of evolution by natural selection using observations, experimentation, discussion, geology and fossils.
- B.Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Theory of evolution (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 describe how Darwin developed the theory of evolution by natural selection using observations, experimentation, discussion, geology and fossils.
- D.Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than The development of understanding of genetics and evolution / Theory of evolution (biology only).
