Answer
The major events in each stage of mitosis are as follows:
Solution
a
Prophase: Chromatin condenses into visible chromosomes, and the nuclear envelope begins to disintegrate. The mitotic spindle starts to form
b
Metaphase: Chromosomes align at the metaphase plate (the cell's equatorial plane). Spindle fibers attach to the centromeres of the chromosomes
c
Anaphase: Sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell
d
Telophase: Chromatids reach the poles, and the nuclear envelope re-forms around each set of chromosomes. The chromosomes begin to de-condense back into chromatin
e
Cytokinesis: The cytoplasm divides, resulting in two daughter cells, each with a complete set of chromosomes
Key Concept
Mitosis stages
Explanation
Mitosis is a process of cell division that ensures equal distribution of chromosomes to two daughter cells. Each stage has distinct events that facilitate this process.
