Intro to Mitosis

Monday January 28th
During the S phase of interphase DNA is replicated.  At his point we have made duplicated chromosomes.  These will then be split apart in a process known as mitosis.  Mitosis ONLY occurs in Eukaryotic Cells.  With this information we can infer that mitosis is the division of the Nucleus which stores genetic information in Eukaryotic cells.

There is actually a LOT we can learn/recall from this question.  Today I encouraged more of the THINKING behind the question than the answer itself.  The FIRST place your mind should have gone is determining what OTHER type of cell there is (since I told you that this occurs in Eukaryotic cells).  The other type of cell is prokaryotic.  The next place to go then is recalling the difference between eukaryotic and prokaryotic cells.  There are a couple differences between the two, but since I am asking about a part of the cell that "Stores genetic information" this should have jogged your memory that only Eukaryotic cells have a nucleus.  Therefore the answer was nucleus.
After that I had you at least write the stages of mitosis.  Tomorrow and the next day we will actually discuss these notes and work through a couple demonstrations to help you learn it.
