Interphase (Preparation)
|
The cell spends most of its time in interphase, this is where duplication of the chromosomes occurs. The cell also copies all of its organelles and phospholipids for cell membrane material.
|
|
|
Prophase (First)
|
Chromatin (DNA & protein) condenses into visible chromosomes. Centrioles move to opposite sides of the cell. Nuclear membrane dissolves by late prophase and microtubule proteins grow from centrioles.
|
|
|
Metaphase (Second)
|
Chromosomes line up at the metaphase plate in the center of the cell. Kinetochore attaches to the center of the chromosome, attaching the chromosome to microtubule strands.
|
|
|
Anaphase (Third)
|
Chromosomes separate, becoming sister chromatids. As they move to opposite ends of the cell as the kinetochore microtubules shorten.
|
|
|
Telophase (Fourth)
|
Chromatids have arrived at opposite ends of the cell, nuclear membrane reforms, chromatids decondense and look like spaghetti strands. Spindle fibers (microtubules) disappear.
|
|
|
Cytokinesis (Fifth)
|
Division of the cytoplasm. Animal cells: Actin protein pinches the cell in forming two. Cleavage furrow is visible. Plant cells: Vesicles bring cell membrane material to cell plate in between two cells.
