Mitosis

You are made of trillions of cells. Inside each cell there's a nucleus and the nucleus stores your DNA. The nucleus in your cell controls everything that goes on in your cell. Mitosis means one cell splitting in to two. Mitosis was first observed by a German biologist by the name of Walther_Flemming who in 1878 was studying the tissue of salamander gills and fins. You have 46 chromosomes grouped into 23 pairs one from your mom the other is from your dad cells with all 46 pairs are called diploid cells. Half of the Diploid cells are called Haploid cells.
