Click on above link read the page and then hit next.

Complete the following statements using the page with the steps of mitosis.

11.  The DNA duplicates during interphase to prepare for ____________.

12.  Chromatin in the nucleus begins to condense and becomes visible in the light microscope as ________________.

13.  Spindle fibers align the chromosomes along the _________ of the cell nucleus.

14.  The paired chromosomes ___________ at the kinetochores and move to opposite sides of the cell.

15.  New ____________ form around the daughter nuclei while the chromosomes disperse and are no longer visible under the light microscope.

Click Next and copy the table down as asked. 

On this page you must look at the picture of the cell and determine which phase it is in.  You then click on that phase. (they are listed below the photo in blue)  Continue to identify the cells until you are complete.  Then complete the chart that you copied. 

To determine the percentage for each phase take the total # of cells found in that phase and divide it by the total number of cells in all of the phases, which happens to be 36 in this case, then multiply by 100 and this is the percentage.  There is a calculator on your computer: Click on the start menu and go to all programs then go to accesories the calculator should be located here.
