Study Notes
- Mitosis is a process of cell division that allows for the regeneration of body parts by separating nuclear chromosomes into two identical daughter nuclei.
- The process of mitosis consists of four key phases: prophase, metaphase, anaphase, and telophase, followed by cytokinesis.
- Before entering mitosis, a cell undergoes a period of growth and rest called interphase where genetic material increases.
- During prophase, chromatin condenses to form chromosomes with two sister chromatids, the nucleolus disappears, and the nuclear membrane breaks down.
- In anaphase, sister chromatids separate at the kinetochore and move towards opposite poles, while cytokinesis partitions the cytoplasm either through cleavage furrow in animals or cell plate formation in plants, resulting in two daughter cells.
