Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. 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. Common misconception: Explaining protein coding without naming the gene as the relevant section of DNA. This would blur DNA vs genes instead of testing DNA and the genome.
- C. Partial misconception: Treating DNA as if it always means one gene. 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. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / DNA and the genome.
Answer
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. 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 Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. 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.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. 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 A DNA base sequence is the storage format; a gene is the named instruction unit. 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 explaining protein coding without naming the gene as the relevant section of dna., treating dna as if it always means one gene., or drift away from do not use dna, gene, and chromosome as interchangeable answers..
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.
