Question
- A. Use the cell-cycle checkpoint to explain why mitosis preserves chromosome number after DNA replication; then apply mitosis vs meiosis: mitosis maintains chromosome number in body cells, whereas meiosis halves chromosome number for gametes and link the evidence directly to Compare outcomes of mitosis and meiosis.
- B. Ignore the cell-cycle checkpoint and give only a memorised sentence about the topic.
- C. Treat every genetic term as interchangeable and avoid explaining DNA, chromosome or protein evidence.
- D. Use the conclusion first, then leave out the molecular or inheritance evidence.
Answer
The correct answer is: Use the cell-cycle checkpoint to explain why mitosis preserves chromosome number after DNA replication; then apply mitosis vs meiosis: mitosis maintains chromosome number in body cells, whereas meiosis halves chromosome number for gametes and link the evidence directly to Compare outcomes of mitosis and meiosis.
Explanation
The response is creditworthy because it uses a distinct evidence source (cell-cycle checkpoint), performs the required task, and states the relevant boundary: mitosis vs meiosis: mitosis maintains chromosome number in body cells, whereas meiosis halves chromosome number for gametes. It stays anchored to Compare outcomes of mitosis and meiosis.
Common mistake
Genetic diversity can arise as a result of mutation or during meiosis common mistake 1
Giving a vague answer instead of directly addressing: Compare outcomes of mitosis and meiosis..
Answer by clearly explaining how to compare outcomes of mitosis and meiosis..
