There are 23 pairs of chromosomes in a diploid human body cell. Only two pairs of chromosomes are shown in the diagrams below.
The stages of mitosis are: prophase, metaphase, anaphase and telophase. The cell membrane pinches in and eventually divides into two daughter cells. New membranes form around the chromosomes at each end of the cell. The membrane around the nucleus disappears.Ĭhromosomes and their copies line up in the middle of the cell.Ĭhromosomes and their copies are pulled to different ends of the cell. The DNA in chromosomes and their copies condenses to become more visible. The DNA in chromosomes copies itself ready for mitosis.
The cell spends most of its life in this phase. Every base pair of their DNA is identical.
The daughter cells are clones of each other.
