Question
- A. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics.
- 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 Selective breeding.
- C. Partial misconception: Treating DNA as if it always means one gene. This misses the objective focus on describe selective breeding as humans breeding plants and animals for particular genetic characteristics.
- D. Terminology mix-up: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Selective breeding.
Answer
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Selective breeding.
Explanation
The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics, so the answer must stay inside Selective breeding. 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
Selective breeding common mistake 1
Giving a vague answer instead of directly addressing: Describe selective breeding as humans breeding plants and animals for particular genetic characteristics..
Answer by clearly explaining how to describe selective breeding as humans breeding plants and animals for particular genetic characteristics..
