1. What is the primary role of the nucleus in relation to cell division?
- A. To store genetic information in the form of chromosomes
- B. To produce energy for the cell division process
- C. To manufacture ribosomes for protein synthesis
- D. To control the movement of the cell membrane
2. Which of the following correctly describes the main outcome of mitosis?
- A. Production of four genetically different haploid cells
- B. Production of two genetically identical diploid daughter cells
- C. Reduction of chromosome number by half
- D. Exchange of genetic material between homologous chromosomes
3. A cell undergoes uncontrolled division and accumulates genetic mutations. What condition would this lead to?
- A. Programmed cell death
- B. Increased DNA replication
- C. Cancer
- D. Mitotic checkpoint failure only
4. During the cell cycle, a cell increases in size, replicates its DNA, and then divides. Which sequence correctly orders these events?
- A. Mitosis → DNA replication → Growth
- B. Growth → DNA replication → Mitosis
- C. DNA replication → Growth → Mitosis
- D. Growth → Mitosis → DNA replication
5. Meiosis produces four haploid cells whilst mitosis produces two diploid cells. How does genetic variation arise specifically through meiosis, rather than mitosis?
- A. Meiosis involves two divisions, reducing chromosome number progressively
- B. Meiosis produces genetically different cells through independent assortment and crossing over of homologous chromosomes
- C. Meiosis involves more rounds of DNA replication than mitosis
- D. Meiosis produces cells that undergo immediate fusion with other cells
