Variation and evolution
Question
- A. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe bacterial cells engineered to produce useful substances such as human insulin.
- B. Scale confusion: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing Genetic engineering.
- C. Process confusion: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on describe bacterial cells engineered to produce useful substances such as human insulin.
- D. Evidence confusion: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Genetic engineering.
Answer
The correct option is Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe bacterial cells engineered to produce useful substances such as human insulin.. 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 Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe bacterial cells engineered to produce useful substances such as human insulin.. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Genetic engineering because students must describe bacterial cells engineered to produce useful substances such as human insulin. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must describe bacterial cells engineered to produce useful substances such as human insulin, 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 bacterial cells engineered to produce useful substances such as human insulin..
Answer by clearly explaining how to describe bacterial cells engineered to produce useful substances such as human insulin..
