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.

Answer the questions as best you can. The boxes will expand
type if you need more space. (Don't worry if it is a one word answer.
The box size is standard.)
Since you will be working in groups, put all the names of
people in the
group in the box. The ideal group size is 2. As an exception I will
allow groups of 3. No groups of 4 or 5. If you work as a group of 3 I
expect better answers. Group sizes above 3 will be penalized in the
grading. Anyway, there is no place to put more names!
You are encouraged to work in pairs
1 Name: IDNumber:
2 Name: IDNumber:
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
This is a relatively long
assignment (there are many blanks). Pace yourself, but don’t get
distracted. There is more to do besides just reading the tutorials.
You are encouraged, but not
required to work in pairs. If you do not "submit" it electronically, I
won't get the work!
1-Go to the Arizona
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 tab (Ctrl-N) and
following the link from only one window.
2-Within this site you
will do several things. Please note that this site is intended for
college students, and may include vocabulary you will have trouble
with. Do not hesitate to ask for definitions.
3-Click on “Cell Cycle
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 questions:
Q-1: Define Chromatin:
does the G stand for in G1 and G2?
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
paste. I know the standard descriptions. Explaining in your own words
will convince me you understand. (THIS IS THE BULK OF THE GRADE!)
6-Go back to the Cell Biology Page
and in the left hand column there is an activity: Onion Root Tips.
Click on that.
7-Read and follow the “next” until
you get to the table, which I have copied below for you.
number of cells
percent of cells
After you carry out the on-line onion root tip lab, record
data in this table.
