Mitosis Stages Flashcards

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.
