Study Notes
Mitosis Stages Overview
- Mitosis is a process of cell division that ensures equal genetic distribution to daughter cells.
- It includes several distinct phases: Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
- The cell cycle phases include Interphase (G1, S, G2) and the M Phase (mitosis and cytokinesis).
Prophase
- Marks the beginning of mitosis.
- Chromosomes condense, becoming visible under a microscope.
- The nuclear envelope begins to break down.
Metaphase
- Chromosomes align at the cell's equatorial plane, known as the metaphase plate.
- Spindle fibers attach to the centromeres of chromosomes, preparing for separation.
Anaphase
- Chromatids are pulled apart toward opposite poles of the cell by spindle fibers.
- Ensures that each daughter cell will receive an identical set of chromosomes.
Telophase
- Two separate nuclei form in the cell, one for each set of chromosomes.
- The cell begins to take on an hourglass shape as it prepares for division.
Cytokinesis
- The final step in cell division where the cytoplasm is divided, resulting in two distinct daughter cells.
- In animal cells, this occurs through cleavage furrow formation; in plant cells, a cell plate forms.
Interphase
- The preparation stage of the cell cycle consisting of G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis).
- Although not part of mitosis, it is crucial for cellular preparation.
M Phase
- Comprises all stages of mitosis along with cytokinesis.
- Represents the shortest phase in the cell cycle focused on division.
