3. Perform "Multiple Sequence Alignment" of these proteins in Biological Workbench. Give the results of MSA. You should use organism name instead of ID number for each protein.

The results are HERE.


4. Show color-coded plot of alignment.

You could find a postscript version HERE.





















5. Show the results of the rooted phylogenetic analysis.
