All chromosomes found in the nucleus of the cell. The nucleus is surrounded by a membrane called the nuclear envelope.
2 of 7
Stage 2
Before mitosis begins, each chromosome duplicates to consist of 2 strands called chromatids. The chromatids condense - shorter, thicker and more visible through a microscope.
3 of 7
Stage 3
The nuclear envelope disappears and the spindle forms at the poles. The chromosomes line up at the equator.
4 of 7
Stage 4
The spindle fibres contract, pulling the 2 chromatids apart - one to 1 pole of the cell and one to the opposite pole.
5 of 7
Stage 5
The nuclear envelope forms around each new set of chromosomes, and the cell itself start to divide - amount of cytoplasm increases.
6 of 7
Stage 6
The cell finishes dividing in 2 and the chromosomes decondense, making them become longer and thinner. Both cells contain 46 chromosomes, and are identical.
