What is it?
This series of images depicts the process of mitosis in the early embryo of the fruit fly, Drosophila melanogaster. In this stage of Drosophila development, nuclei divide very rapidly without cell division and the divisions are synchronized. The mitosis you see here took about 10 minutes from start to finish.

  • Microtubules are shown in red, nuclei in green.
  • Each nucleus is about 5 micrometers across (a micrometer, also called a micron, is 1/1,000,000 of a meter).

Make a flipbook of mitosis
    You will need:
  • 5 sheets of stiff 8.5 x 11 inch computer printer paper (cardstock or heavy photo paper work well)
  • a computer printer that will accept the heavy paper
  • a medium-sized binder clip
  • scissors

3 Print each of the 5 PDF pages onto a sheet of 8.5 x 11" heavy paper (the files are in color, but you can print them in black and white, too).

4 Cut the flipbook pages on the dotted lines, including the blank pages on page 5. (Tip: To save time, cut the edges off of each sheet first; then cut down the center line, stack the two halves on top of each other, and cut out the individual "frames").

5 Stack the pages in order; add at least 5 blank pages to the end (this helps the book "flip" well).

6 Tap the stack of pages on a tabletop to make sure the right hand sides are lined up.

7 Clip Use the binder clip on the left side of the stack to hold your book together.

8 Flip!
