Variation and evolution
Question
- A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe crop plants engineered for disease resistance or bigger and better fruits.
- B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Genetic engineering.
- C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on describe crop plants engineered for disease resistance or bigger and better fruits.
- D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Genetic engineering.
Answer
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe crop plants engineered for disease resistance or bigger and better fruits.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Genetic engineering.
Explanation
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe crop plants engineered for disease resistance or bigger and better fruits.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe crop plants engineered for disease resistance or bigger and better fruits. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must describe crop plants engineered for disease resistance or bigger and better fruits, so the answer must stay inside Genetic engineering. 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
Genetic engineering common mistake 1
Giving a vague answer instead of directly addressing: Describe crop plants engineered for disease resistance or bigger and better fruits..
Answer by clearly explaining how to describe crop plants engineered for disease resistance or bigger and better fruits..
