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.
