In What Ways do Cells Change in Response to a Dynamic Environment?
Why?
After a week on the beach?

Same caterpillar... Why?

Why?
Same flamingo...

Same fly...
Why?

Why?
Same plant...

Identical Twins
Same DNA, different fingerprints
How can this be?

Which part(s) can change temporarily?

Mount St. Helens
WHY does a changing environment have an influence on cells?
What mechanisms are in place to allow cells to change?
How can WE test these?Nasa.gov

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!

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.

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

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?
