• Same DNA, different fingerprints
• How can this be?

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!

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.

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

• 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?
