Cell division / mitosis

Chromosomes

Long strands of DNA containing genes. Found in 23 pairs in a human

Cell cycle

The process a cell goes through to divide

Mitosis

A type of cell division that creates 2 identical daughter cells

Therapeutic cloning

producing an embryo with the same genes as the patient

Mitosis stage 1

DNA replicates to form two copies of each chromosome. The cell grows and the number of ribosomes and mitochondria increase

Mitosis stage 2

one set of chromosomes is pulled to each end of the cell and the nucleus divides

Mitosis stage 3

the cytoplasm and cell membrane divides to produce two identical daughter cells

How is mitosis important?

It is important in the growth and development of multicellular organisms e.g. tissue repair and reproduction
