Question
Page 393 Question 4: Describe mitosis.
Answer
Mitosis is a process of cell division in which a single cell divides into two identical daughter cells, each having the same number of chromosomes as the parent cell. It consists of four stages: prophase, metaphase, anaphase, and telophase. During prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down. In metaphase, the chromosomes align at the equator of the cell. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, in telophase, the nuclear envelope reforms around the chromosomes, and the cell divides into two daughter cells.
