Explanation
Mitosis Features in Cell Cycle
Steps:
- Identify mitosis as eukaryotic nuclear division for somatic cells, producing two identical nuclei.
- Recall key features: equational division, occurs in diploid cells, conserves chromosome number.
- Evaluate options based on standard mitosis traits: no genetic variation, no haploid outcome.
- Select option matching only the accurate feature (2).
Why D is correct:
- Mitosis is defined as equational division maintaining chromosome number (2n to 2n), per cell biology principles.
Why the others are wrong:
- A includes all, but 1 and 3 misrepresent mitosis as reductional or variable.
- B includes 1, which incorrectly implies haploid production.
- C includes 3, which falsely suggests genetic recombination.
Not enough information on statements 1 and 3 for full verification.
Final answer: D
