Study Notes
Mitosis Overview
- Mitosis is crucial for growth and development in living organisms, evident in processes such as a tiger cub's growth.
- It results in two identical daughter cells, each with an identical copy of DNA.
Key Stages of Mitosis
- Centromeres split apart during anaphase, allowing the sister chromatids to separate.
- Early in mitosis, the nucleus, nucleolus, and nuclear envelope dissolve, which is reversed in the telophase stage.
- Chromosomes first become visible during prophase due to the coiling of chromatin.
Cytokinesis
- Cytokinesis occurs during mitosis, finalizing cell division after nuclear division is complete.
- The end result of cytokinesis is two cells, each containing identical DNA.
Cancer Cell Characteristics
- Cancer cells exhibit uncontrolled growth and lack regulation from contact inhibition, leading to abnormal cell proliferation.
Interphase Replication
- During interphase, chromosomes replicate to ensure each new cell has the necessary genetic information post-division.
Real-world Examples
- An example of mitosis in action can be seen in growing leaves, which demonstrate the process of cell division in plants.
