  1. Environmental Influence on Gene Networks Lesson 1: Introduction Created through a partnership between teachers, students and scientists

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

  3. In What Ways do Cells Change in Response to a Dynamic Environment? Same caterpillar... Why?

  4. Same flamingo... Why?

  5. Same fly... Why?

  6. Same plant... Why?

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

  8. Which part(s) can change temporarily?

  9. 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 Mount St. Helens

  10. Model Organisms Somebiological processes operate exactly the same in many different organisms. Halobacteriumsalinarum 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 salinarumis 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?
