2. Intro!
Mitosis is a type of cell division that produces genetically identical cells.
During mitosis DNA replicates in the parent cell, which then divide to produce two new cells, each containing an exact copy of DNA in the parent cell.
The only source of genetic variation in cells is via mutation .

3. Process
Mitosis has 5 stages

4. 1st stage This stage is called Interphase.
During this stage, the DNA has been replicated, although it has not yet formed a condensed structure of a chromosome. Instead they remain as loosely coiled chromatin.
Chromatin is ; Ribbon-like twists of DNA molecules in the nucleus of the interphase.
The nuclear membrane is still intact to protect the DNA molecules from undergoing mutation.

5. 2nd stage This stage is called Prophase
The DNA molecules progressively shorten and condense by coiling, to form chromosomes. The nuclear membrane and nucleolus are no longer visible.
The centrioles migrates to either sides of the poles of the cell. These produce spindle fibres

6. 3rd stage This stage is called Metaphase
The spindle fibres attach themselves to the centromeres of the chromosomes and align the chromosomes at the equatorial plate.

7. 4th stage This stage is called Anaphase
The spindle fibres shorten and the centromere splits, separated sister chromatids are pulled along behind the centromeres.

8. 5th stage
Telophase
The chromosomes reach the poles of their respective spindles. Nuclear envelope reform before the chromosomes uncoil. The spindle fibres disintegrate.

9. 6th Stage This stage is called Cytokinasis
This is the last stage of mitosis. It is the process of splitting the daughter cells apart. A
furrow forms and the cell is pinched in two. Each daughter cell contains the same number
and same quality of chromosomes.
