Study Notes
- Interphase occurs when a cell is not dividing but is performing its normal functions.
- During interphase, a cell grows, produces more organelles, and replicates its DNA in preparation for division.
- Mitosis is the process of cell and nuclear division for somatic cells (body cells).
Four Stages of Mitosis
- Prophase: Chromatin condenses into chromosomes, and the nuclear envelope breaks down.
- Metaphase: Chromosomes align in the middle of the cell with the help of the cytoskeleton (centrioles and spindle fibers).
- Anaphase: Chromosomes are pulled apart toward opposite poles.
- Telophase: Chromosomes unwind, the nuclear envelope reforms, and a cleavage furrow forms as the cell prepares to divide.
- Cytokinesis is the final stage where two cells separate, although epithelial cells remain close to each other.
