Question
- A. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must discuss the importance of understanding the human genome for finding disease-linked genes, understanding inherited disorders and tracing human migration patterns.
- B. Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing DNA and the genome.
- C. Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on discuss the importance of understanding the human genome for finding disease-linked genes, understanding inherited disorders and tracing human migration patterns.
- D. Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA and the genome.
Answer
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must discuss the importance of understanding the human genome for finding disease-linked genes, understanding inherited disorders and tracing human migration patterns.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in DNA and the genome.
Explanation
The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must discuss the importance of understanding the human genome for finding disease-linked genes, understanding inherited disorders and tracing human migration patterns.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches DNA and the genome because students must discuss the importance of understanding the human genome for finding disease-linked genes, understanding inherited disorders and tracing human migration patterns. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must discuss the importance of understanding the human genome for finding disease-linked genes, understanding inherited disorders and tracing human migration patterns, so the answer must stay inside DNA and the genome. 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
Misunderstanding the Human Genome's Role
Students often think that understanding the human genome only helps in finding disease-linked genes, neglecting its role in tracing human migration patterns.
Emphasize that the human genome is crucial for multiple applications, including understanding inherited disorders and tracing migration patterns, not just disease identification.
