We each start out as a single cell. To develop different organs and tissues for the body to grow, our cells must multiply. As adults, cells need to be replaced when damaged or when they complete their life cycle.

Mitosis

The body produces new cells by a process called mitosis. This is when a cell’s DNA, which carries all the instructions to build and run a new cell, duplicates itself. The cell then splits to form two identical cells. This is how cells grow – by making exact copies of themselves.

Checking

The parent cell gets ready for mitosis. It checks its DNA for damage and makes any necessary repairs.

Preparation

The chromosomes duplicate themselves, then the originals join together with their copies.

Lining up

Each doubled chromosome attaches to special tribes, which help them to line up in the centre of the cell.

Separation

The chromosomes break apart at the point where they were attached. Each half is pulled to the opposite end of the cell.

Splitting

A membrane forms around each group of chromosomes. The cell membrane starts to pull apart to form two cells.

Off spring

 Two daughter cells are formed. Each one contains a nucleus with an exact copy of the DNA from the parent cell.
