|Your Name (if you are
working pairs, both names):
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.
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.
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.
As you carry out the on-line onion root tip lab, record your data in this
Q-4: In which
phase does a cell spend most of its time?
N.B. You will do something just like this as a lab in class.
So, this is a "pre-lab."
You should also refer to the Biology Place Lab Bench to
"pre-lab" the lab.
8-Go back to the Cell Biology Page. Go to the meiosis tutorial, and again
follow the “next” to learn about meiosis. When you have gotten to the
questions, go back to the page with the link to the 2 karyotype activities.
9-Go through the karyotype activity and for each patient record the
proper notation and the diagnosis.
Q5-What do you
think of the Arizona Biology Project’s web tutorials?
