This is all the information on DNA and Mitosis and Meiosis.

Hope they help will be making many more for the other topics. I have remebered all this information off by heart for my exam! so can you!!

What does Mitosis do?
Mitosis is used for growth and repair of cells, it makes copies of each chromosome one from mother and one from father. Mitosis is used in Asexual reproduction which means that the offspring has exactly the same genes and there is no variation.

What does Meiosis do?
Meiosis is when they have half the normal number of Chromosomes because of Gametes(sex cells) you get one from each parent so 23 pairs from each which when joined together form 46 chromosomes this is how many you have altogether.
