Mitosis - Reflexions

Mitosis

The cells of eukaryotic organisms contain a nucleus which encloses the chromosomes in which are contained the genes, the cells’ genetic material. When the latter divide, their nuclei also divide. It is this act of nucleus division which is called mitosis. By extension, mitosis designates cell division itself. Mitosis is thus an essential phenomenon and has the task of reproducing identically (unless there is an accident!) the whole of the genetic material – genome – of each cell and to transmit this material to two daughter cells. This type of reproduction thus ends up in forming genetically identical clones (apart from the accidents which can occur during the reproduction of the genome).
