Study Notes
Cell Division Functions
- Cell division is essential for growth, replacing aging cells, and reproduction in organisms.
Mitosis
- Involves somatic cells (body cells), resulting in two genetically identical daughter cells.
Meiosis
- Involves germ cells and produces unique cells such as eggs or sperm.
- One germ cell produces four unique cells during meiosis.
- Only occurs in germ cells.
States of DNA
- Chromatin: Loosely coiled DNA, not visible under a light microscope.
- Chromosomes: Tightly coiled DNA, visible during cell division.
- DNA must replicate before cell division to ensure each daughter cell receives a complete copy of genetic information.
