Mitosis

This week in class we modeled the process of mitosis by using yarn and string. I would definitely use this in my classroom someday because it was really hands on and I could really see what was happening in each step. 

 First, the cell is in interphase. It is just doing cell things and not dividing. The DNA is represented by the little pieces of yarn.

Next, the cell begins replication. They create another DNA strand that is identical to the first.

Then, the cell enters prophase. In this stage, spindle fibers (the strings) connect to the centrioles to the chromosome. 

Here, the cell is in metaphase. The chromosomes all line up across the middle of the cell. 

Now the cell is in anaphase. The spindle fibers are shortening and pulling the identical chromosomes apart.









Finally, the cell goes through telophase. The DNA starts to turn back into chromatin, two nuclear membranes form, and the spindle fibers disappear.





Then the cell is in cytokinesis. The cell separates into two cells.
