Mitosis!
Telo=Two
1. 2 nuclei begin to form with the same amount of chromatids in each nuclei.
Interphase is the first phase of The Cell Cycle. During this phase, the cell prepares to divide into two cells by copying it's DNA and enlarges itself.
2. The nuclear membrane will begin to grow again.
cell division process
3. The nucleolus will appear again.
Mitosis -
happens
in all cells
- Mitosis is NOT the longest
phase of the cell cycle
- There are 4 different phases of Mitosis(Prophase, Metaphase, Anaphase, Telophase)
Metaphase!
Mitosis:
Spindle fibers
S
Phase
Centriole
Chromosomes
The cell duplicates all of it's chromosomes. For humans, it would go from 23 to 46.
Meta=middle
Phase
G
1
1. The chromosomes line up in the middle.
2. Spindle fibers attach to the centromeres.
For this phase, the cell grows to it's needed
size and creates the structures it needs.
Prophase!
Mitosis:
a chromatid is 1/2
of a chromosome
During Anaphase, centromeres split and sister chromatids are pulled apart to opposite poles of the cell. Each chromotid is now a separate chromosome
1. Nuclear envelope dissapears
2. Chromosomes condese- can see sister chromotids and centromere
Cytokinesis!
Ana = Apart
3. The nucleolus inside the nucleus disappears.
In cytokinesis cytoplasm divides and 2 new daughter cells are now separate.
4.The spindle fibers start shooting out of the centrioles.
Chromatids
The Cell Cycle
Mitosis:Anaphase!
In this phase, the cell checks itself for any missing organelles and increases the amount of cytoplasm, so when the cell becomes two, there is enough for both.
After this, the cell is prepared to go on to the cell division.
