- B.Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Classification of living organisms.
- C.Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on describe the traditional classification of living organisms into groups using structure and characteristics.
- D.Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Classification of living organisms / Classification of living organisms.
