Cell Cycle Mini-Poster Project
Directions: You will create a mini-poster which follows 4 chromosomes through
the process of mitosis. You will be quizzed on the poster upon its completion so
be careful and pay attention to your work. DETAIL, NEAT, COLORFUL
POSTERS!
Poster Requirements:
1. You must have the following title: The Cell Cycle
2. 4 chromosomes are represented….each a different color (one yellow, one
blue, one green, and one orange).
3. You must have 14 pre- labeled diagrams representing the cell cycle :
Interphase (2 boxes): look in your notes for description of what to draw.
Note that you want the boxes that have one cell (which one comes first?)
Early prophase: Chromatin is now replicated chromosomes (4 different
colors). 2 Pairs of centrioles begin to move to opposite ends of the cell.
Spindle fibers begin emerging from
centrioles.
Middle prophase: Nuclear envelope
starts to break down and the nucleolus
disappears. Spindle fibers elongate
and are reaching for the chromosomes.
Centrioles have almost reached the
ends of the cell.
Late prophase: Centrioles are now
on opposite ends of the cell. Spindle
fibers now have extended long enough
that they and have attached to the
centromere of each sister chromatid.
Nuclear membrane is gone for the most part at this point.
Early Metaphase: Spindle fibers are now firmly attached to the
centromeres of each chromosome. The “tug of war” has begun and the
spindle fibers are “violently pulling” the chromosomes towards the center
of the cell. Show them starting to move toward the middle of the cell.
Late Metaphase: The spindle fibers have pulled the chromosomes and
they have finally lined up at the metaphase plate in the correct orientation
(check your spindle attachments).
Early Anaphase: Centromeres split and spindle fibers start pulling the
sister chromatids apart to become individual chromosomes. The sister
chromatids are being pulled to the opposite sides of the cell ( the poles).
Draw an arrow showing the direction they are being pulled!
Late Anaphase: The sister chromatids are now individual chromosomes
(single propeller) and have now almost reached the end of the cell and are
closest to the centrioles (which have reeled them in).
Early Telophase: Nuclear envelop starts to re-forms around nucleus and
the chromosomes now start to uncoil (deflated balloons) not quite
chromatin yet. cell starts to pinch in a little. Spindle fibers have broken
down and are not around the centrioles.
Late Telophase: Nucleolus has reappeared in each new nucleus. The
chromosomes are now chromatin (squiggles and should look like
chromatin in first interphase picture). Cell starts to pinch in (this has been
done for you).
Early Cytokinesis: Cleavage furrow begins to form causing more of the
cell to pinch in.


animal cells: cell membrane pinches in even more to produce a
cleavage furrow & finally divides
plant cells: the cell pinches in even more to produce a cell
plate, a new cell wall.
Late Cytokinesis: 2 daughter cells are now formed each with their own
distinct nucleus, nucleolus, chromatin, and a set of centrioles at the ends
of the cells.
**Under each circle write a description of what is happening**
