15 your Division” sheet. The spindle fibers (white string) should “Cell be touching the spindle apparatus on each side (see image). Take (with a camera) OR draw a picture of your metaphase 16 in Part A of the analysis section and answer the questions. Anaphase: The spindle apparatus pulls the spindle fibers toward themselves, causing 17 each chromatid to pull away and separate to opposite sides of the cell. In this simulation, your are going to be performing the action 18 of the spindle apparatus by pulling the spindle fibers. Move the chromosomes and spindle fibers to the center of the anaphase cell on your Division” sheet with the same set-up as the “Cell metaphase cell. Pull the spindle fibers slowly toward each spindle apparatus. This 19 should cause the chromatids to separate and move toward opposite sides of the cell (see image). Once the chromatids the spindle apparatus on each side, take (with a camera) OR 20 draw a picture of your anaphase model in Part A of the analysis section and answer the questions. Now that the chromatids have separated, the cell will to reform a nucleus Telophase: 21 to protect the DNA. The spindle and spindle fibers release the chromatids and begin to be broken down by the cell. The cell begins to split its cell membrane and cytoplasm in half to begin the formation of two cells. 22 Remove (untie) the spindle fibers from each chromatid. Move the chromatids to the telophase cell on your Division” “Cell 23 sheet. Place the separated chromatids in both of the reforming nuclei (see image). Take (with a camera) OR draw a picture of your telophase model in 24 Part A of the analysis section and answer the questions. Cytokinesis: The cell has separated and formed two completely new cells. The 25 chromatids unwind back into chromatin so the DNA can be used to create proteins.
