Part of eukaryotic cell division during which the cell nucleus divides.
1 of 6
Interphase
The cell carries out normal functions, but also prepares to divide. The cell's DNA is unravelled and replicated, to double its genetic content. The organelles are also replicated so it has spare ones, and its ATP content is increased (ATP provides energy

1. Prophase
The chromosomes condense, getting shorter and fatter. Tiny bundles of protein called centrioles start moving to the opposite ends of the cell, forming a network of protein fibres across it called the spindle. The nuclear envelope breaks down and chromosom

2. Metaphase
Two chromosomes (each with two chromatids) line up along the middle of the cell and become attached to the spindle by their centromere.

3. Anaphase
The centromeres divide, separating each pair of sister chromatids. The spindles contract, pulling chromatids to opposite poles of the spindle, centromere first. This makes the chromatids appear V-shaped.

4. Telophase
The chromatids reach opposite poles on the spindle. They uncoil and become long and thin again. They're now called chromosomes again. A nuclear envelope forms around each group of chromosomes so there are now two nuclei. The cytoplasm divides (cytokinesis
