Study Notes
Mitosis Overview
- Mitosis occurs in body cells, unlike sperm and egg cells which undergo meiosis.
- Essential for replacing damaged cells and facilitating growth in organisms.
Importance of Mitosis
- Mitosis allows for cellular repair, restoring function to damaged tissues.
- Promotes growth by increasing cell numbers during development and tissue expansion.
Cell Characteristics
- Mitosis creates cells that are identical to the original cell, ensuring genetic consistency.
- The process does not produce genetically diverse cells; it guarantees uniformity.
Consequences of Imbalance in Cell Cycle
- If cells spend excessive time in mitosis rather than interphase, toxins may accumulate, leading to cancer.
- Continuous division can result in unnecessary growth and the formation of tumors.
Chromosome Structure
- Chromosomes are composed of protein and DNA, essential for proper genetic information distribution.
- Each chromosome plays a critical role during cell division by ensuring equal distribution to daughter cells.
Human Chromosome Count
- Human somatic (body) cells are diploid, containing 46 chromosomes (23 pairs).
- After mitosis, diploid cells retain the original chromosome count, supporting genetic stability.
