You might want to actually write your answers in Word (so
spell check them) and then cut-and-paste into the boxes. That way, if
the computer misplaces your work you can just re-paste the answers.
Since you may work on this over more than one day, and you
at home, I will keep track of what
you have done. Feel free to click submit as you work to save your work

The box size is standard.)
The ideal group size is 2. As an exception I will
allow groups of 3. If you work as a group of 3 I
expect better answers. Group sizes above 3 will be penalized in the

Your answers will have to be perfect for a group size of 3
not to cost you in the grading. No groups larger than 3 will be

You are encouraged, but

1-Go to the
Biology Cell Biology Education site:
The Biology Project: Cell Biology
This will work best if you open it in a new windows-just clicking
should do it, but if not, try opening a second Explorer (Ctrl-N) and
following the link from only one window.

college students, and may include vocabulary you will have trouble
with. Do not hesitate to ask for definitions.
4-Using the “next”
command at the
bottom of each screen go through the 3 modules in this section (DNA
Basics, The Cell Cycle, Mitosis). Don’t bother with the mitosis
animation-it doesn’t always play well on these machines.
5-Answer the following
Q-1: Define Chromatin:
does the G stand for in G1 and G2? Describe (in order) the stages of
the cell cycle.
Describe the stages of mitosis in words. You should have one sentence
for each stage (that is a minimum of 5 sentences. Don't just cut and

and in the left hand column there is an activity: Onion Root Tips.
Click on that.

you get to the table, which I have copied below for you.
