Term
Name the 5 phases of mitosis in order.
Definition
Interphase, prophase, metaphase, anaphase, and telophase.
Term
Mitosis
Definition
When a cell divides making 2 new cells that are exactly like the original for the purpose of growth, repairing injury to tissue, and maintainance.
Term
Describe interphase.
Definition
The time between divisions, DNA replication occurs at the end of interphase.
Term
Describe prophase.
Definition
The nuclear membrane begins to disappear and the chromosomes split into X-shaped sets of two chromatids. Spindle fiber also starts to form between the centrioles.
Term
Describe metaphase.
Definition
The centrioles are directly opposite each other and spindle fibers form between them. The chromosomes line up in the middle with one on each spindle fiber.
Term
Describe anaphase.
Definition
The spindle fibers pull the chromatids apart.
Term
Describe anaphase.
Definition
The spindle fibers pull the chromatids apart.
Term
Describe telophase.
Definition
1) Nuclear membranes reappear arond chromosomes. 2) Chromosomes unravel into chromatin. 3) Cytokinesis: division of cyoplasm occurs. Animal cells have a cleavage furrow, plant cells have a cell plate.
