Activity
1 - Student Assessment Tools TESTING PHIX174 HOST RANGE
What is a serial
dilution?
Which host
was most compatible with Phi X 174? Which was the second-most compatible?
Were there any that were not compatible at all?
Bacteriophage
Phi X 174 is also known as coliphage Phi X 174. Based on your results, why?
Coliphages
are sometimes used to assess water quality. Research E. coli and explain how
this would make sense. How would you perform the test?
What does a
Phi X 174 particle look like? Try the websites recommended in the sources
section above to find a picture of Phi X 174.
What happens
during a lytic bacteriophage infection? Visit your library or look in your
textbook to find out. Write out each step, then refer to your notes and your
Phi X 174 picture to create a flipbook animation of a typical bacteriophage
infection on 3x5 inch paper.
Xenotransplantation
refers to the transplantation of organs from other animals into humans. In
general, the more similar the donor and recipient species, the better the
organ will function after transplantation. Using you knowledge of host ranges,
explain why it might be a better idea to use more dissimilar organ donor species
instead.
