Question 9

What steps of the cell cycle occur during the M phase

Answer 9

• Mitosis
• Cytokinesis

Question 10

Mitotic apparatus

Answer 10

• Aligns replicated chromosomes
• Separates sister chromatids

Question 11

Karyokinesis

Answer 11

Separation of genetic material in mitotic nuclear division

Question 12

Cytokinesis

Answer 12

Separation of the cell cytoplasm in cellular division that follows karyokinesis

Question 13

Steps of mitosis

Answer 13

1. Prophase
2. Prometaphase
3. Metaphase
4. Anaphase
5. Telophase

Question 14

What occurs during prophase?

Answer 14

• Nuclear membrane breaks down to form small vesicles
• Centrosome duplicates to form daughter centrosomes at opposite ends of cell
• Chromosomes dense into sister chromatids held together by centromeres
