10. Model Organisms Some biological processes operate exactly the same in many different organisms. Halobacterium salinarum processes its genetic material in a way that is very similar to the way humans do! http://www.ucmp.berkeley.edu/glossary/gloss3/dna.html

11. Model Organisms Model organisms are relatively simple, but their properties and functions of interest are similar to those in more complex organisms. Halobacterium salinarum is SAFE for beginning scientists to use.

12. Model Organisms The environment can also be more easily controlled in model organism studies.

13. Explore How Halo Change in a Dynamic Environment Which environmental conditions are characteristic for Halo? What experiment could be feasibly (or fairly easily with our equipment) completed to test how Halo respond to an environmental change?
