Study Notes
Overview of PMAT
- PMAT refers to the four stages of mitosis: prophase, metaphase, anaphase, and telophase.
Prophase
- The nuclear envelope disintegrates, allowing the chromosomes to become visible.
- Chromosomes condense and thicken, each consisting of two sister chromatids.
Metaphase
- Chromosomes align along the equatorial plane (metaphase plate) in the center of the cell.
- This alignment ensures proper separation of chromosomes during the next stage of mitosis.
Anaphase
- Each sister chromatid is pulled apart and moves toward opposite ends (poles) of the cell.
- This separation is critical to ensure each new cell receives an identical set of chromosomes.
Telophase
- The nuclei reform around each set of separated chromosomes, marking the near end of mitosis.
- Chromosomes begin to de-condense, returning to a less coiled state as the cell prepares to divide.
Cytokinesis
- Following telophase, mitosis concludes, and the cell undergoes cytokinesis, where the cytoplasm divides to form two separate daughter cells.
