- Bring up course web site
- Go to Scenario 3

6Scenario 3 Our Story
You Our first defense at CDC
Outbreak
. . . Anthrax?
7Scenario 3 Our Story
8Scenario 3 Our Story
DNA polymerase
9Scenario 3 Our Story
If DNA from bacterium with toxin gene
If DNA NOT from bacterium with toxin gene?

12Scenario 3 Our Story
DG47
13Scenario 3 Our Story
DG47
Maybe its not from the toxin gene??
(Try a different approach)
14Scenario 3 Our Story
DG47
15Never mind Blast, What's the real answer?(Do it
yourself)
16Scenario 3 Our Story
Compare nucleotide sequences by hand
DG47 vs lef
17Scenario 3 Our Story

20Scenario 3 Our Story
Why cant Blast figure outwhat you can plainly
see?
21Scenario 3 How does Blast work?
- Theory behind nucleotide vs nucleotide Blast
- Theory behind protein-protein Blast
- How to get Blast to do what you want
