2 Steps of Mitosis 1. INTERPHASE (between) 2. PROPHASE (first) 3. METAPHASE (middle) 4. ANAPHASE (ana-banana-split) 5. TELOPHASE (two)

3 Chromosomes duplicate Chromosomes condense Chromosomes are now double-stranded and held together by a centromere.

4 Chromosomes are fully visible Nuclear membrane fades Centrioles (cowboys) move to opposite ends of the cell Spindle Fibers (ropes) form

5 Chromosomes line up in the center of the cell Centromeres attach to the spindle fibers.

6 Strands of chromosomes separate and move away from each other.

7 Centrioles & spindle fibers disappear Chromosomes stretch out again Nuclear membrane forms Cytoplasm pinches in to form two identical cells.

8 Results One cell = Two cells (exactly alike) with the same number of chromosomes.

9 Mitosis Tutorial & Animation http://www.biology.arizona.edu/cell_bio/t utorials/cell_cycle/cells3.html http://www.biology.arizona.edu/cell_bio/t utorials/cell_cycle/cells3.html

10 The Science of Microbiology (9 minutes) 1. Why is the discovery of Archaea significant?

11 Cell Division (11 minutes) 1. How might stem cells be used in future research? 2. Describe the process of Mitosis and Meiosis.
