Biotechnology WebQuests:
Log onto http://learn.genetics.utah.edu/content/tech/stemcells/
OR http://learn.genetics.utah.edu/content/tech/cloning/. As always
write your responses on a separate sheet of paper.
1) What is a stem cell?
2) Describe the term differentiation as it relates to biology:
3) What types of molecules does a stem cell need to differentiate? What
relationship do these molecules have with the science of genetics?
4) Drag Stem Cell Guy into the Differentiation Booth and dial #5 for Skeletal
Muscle Cell. What is the scientific name of the cell type Stem Cell Guy
will become?
5) Return to the Differentiation Booth and choose another type of cell. Create
a quiz question from the information given and provide its answer.
6) What are the differences between totipotent, pluripotent, and multipotent
stem cells?
7) What are some sources of stem cells available to researchers today? What
is the advantage of using embryonic stem cells?
8) What types of stem cell therapies are in use today?
9) Research the web for an article published within the past month that
addresses some aspect of stem cell biology. Cite the article and provide a
full paragraph summary of it.
10) What are the similarities and differences between SCNT and embryo
twinning?
11) Is cloning a natural process? Defend your answer.
12) “Click and Clone” to create a mouse clone.
a. Write the detailed steps involved in cloning your mouse.
b. What color coat will your mouse clone be?
13) Why does an enucleated ova which has a somatic cell nucleus within it
need to be “rebooted”?
14) How long would you expect a clone of an 80 year old woman to live?
Explain your answer.
15) What are the differences between gene, therapeutic, and reproductive
cloning?
16) Research the web for an article published within the past month that
addresses some aspect of cloning. Cite the article and provide a full
paragraph summary of it.
