Mitosis and The cell cycle and stem cells

Mitosis and the cell cycle are the process in which cells go through to create new cells there are a couple of steps through out the process. First the cells must make copies of DNA. Starting the process of prophase. After this they go into the Metaphase process and the microtubles start to get kinetochore halfway through the spindle poles.   Then they go into the anaphase stage and they start  to line up in center and make new wall, Tubules start to disappear. Telophase New cells are formed two daughter cells now existe.

Stem cells are what contain all the information on how to grow every part in your body. with certain animal they have an unlimited amount of them but we as humans do not. in this other animals this cells that they have in abundace are used to regrow parts that get cut of or what ever may happen.

Meiosis is slightly different from mitosis the first several steps are the same the dna replicates but when it gets to the metaphase and its starting to get to the anaphase stage the cells divide like they would in mitosis  but instead of dividing the cells equally the mother cells go on one side and the father cell goes to the other and the replicated cell starts to bond in the new daughter cells that have been created then they run there cycle over and over.
