Transcript of The Differences Between Mitosis and Meiosis

Mitosis
Mitosis is the process by which a cell duplicates the chromosomes in its cell nucleus, in order to generate two, identical, daughter nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two daughter cells containing roughly equal shares of these cellular components.
Meiosis is the process by which one diploid eukaryotic cell divides twice to generate four haploid cells. In animals, meiosis always results in the formation of gametes. The word "meiosis" comes from the Greek meioun, meaning "to make smaller," since it results in a reduction in chromosome number in the gamete cell.
Mitosis is simple cell division, ending up with two identical cells, each with both pairs of every gene. Meiosis is cell division for gametes (sex cells). This is a two step process, and the four cells that remain each have half the normal cells, so that when the gametes fuse at conception, there will be a new organization of DNA, from both parents.
