Mitosis

-The replication of the nucleus (controlled by DNA)
-Replicate to grow,repair and maintain the cell
-Produces 2 identical daughter cells
-Can be used for asexual reproduction

1

Chromatin

Long thread like strands of DNA

2

Chromosome

-Double,coiled, short DNA
-2 sister chromatids attached at the centromere.

3

Homologous

Identical pairs of chromosomes
Eg. Chromosome 1

4

Somatic cell

Body cell

5

Interphase

This is a preparation stage NOT mitosis or meiosis.
Cell spends most of its life cycle in interphase

6

G1 ( Interphase )

- Growth
- Prep for DNA synthesis

7

Synthesis ( interphase )

DNA replication

8

G2 ( interphase )

Preparation for mitosis

9

Cytokinesis

-Division of the rest of the cell after nucleus divides
-Animal cells: cytoplasm pinches in
-Plant cells: cell plate forms
