Part C - Events of Mitosis vity will test your understanding of events that occur during each phase Now that you have learned the correct order for the phases of mitos Sort the following events into the phase of mitosis that they occur View Available Hint(s) Reset Help DNA condenses into chromosomes Sister chromatids separate into chromosomes Mtoto spindle fibers form and attach to centromeres Nuclear envelope Breaks up Chromosomes move along the spindle fibers Chromosomes reach the opposite ends of the cell Chromosomes relax and nuclear envelopes form Chromosomes align in the center of the cell Completion of cytokinesis Centrosomes move to opposite sides of the cell Prophose Metaphase Anaphase Telophase

Answer 1

Answer

- Mitosis is the stage of cell division where the nucleus divides that results in two identical daughter cells.

- Mitosis occurs in somatic cells.

- The number of chromosomes remain same in the parent and the daughter cells.

- There are four phases in mitosis : Prophase, metaphase, anaphase and telophase.

- The role of mitosis is facilitating cell proliferation and growth of tissues.

Prophase

• DNA condenses into chromosomes
• Nuclear envelop breaks up
• Centrosomes moves to opposite sides of the cell

Metaphase

• Mitotic spindle fibers form and attach to centromeres
• Chromosomes align in the center of the cell

Anaphase

• Sister chromatids seperate into chromosomes
• Chromosomes move along the spindle fibers

Telophase

• Chromosome reach the opposite end of cell
• Chromosomes relax and nuclear envelop form
• Completion of cytokinesis
