Study Notes
M Phase and Cell Division
- Includes mitosis and cytokinesis, collectively known as cell division (M phase).
Mitosis
- Comprises four stages: prophase, metaphase, anaphase, and telophase (PMAT).
- Organizes and distributes chromosomes to daughter cells and is often referred to as nuclear division.
Stages of Mitosis
-
Prophase:
- Chromosomes become visible.
- The nuclear envelope disappears.
- Spindle fibers begin to form.
-
Metaphase:
- Chromosomes align at the cell's equator.
-
Anaphase:
- Sister chromatids are separated and pulled to opposite poles of the cell.
-
Telophase:
- The nuclear membranes start to form around the separated chromosomes.
- The cell begins to undergo pinching, initiating cytokinesis.
Cytokinesis
- The process of cell splitting, resulting in the formation of two distinct daughter cells following mitosis.
Centrioles
- Structures in animal cells that anchor spindle fibers crucial for chromosome separation during mitosis.
Spindles (Spindle Fibers)
- Protein fibers that connect to centromeres of chromosomes to facilitate the separation of sister chromatids during cell division.
