1. Stem Cells and DNA Fingerprinting  Catalyst :  What is the complementary strand of DNA to ACTTGCTACG?  We’ve talked a lot about genetically engineering human beings. Do you think it is morally acceptable to genetically engineer non-human life forms? (Plants, non-human animals, etc.). Explain why or why not.

2. Objectives By the end of today, SWBAT…  Explain how transgenic organisms are created  Describe the costs and benefits of transgenic foods

3. Introduction  As we have learned over the last few days, humans can genetically engineer organisms  Directly alter genes and cells  We haven’t yet reached the point of Gattaca—but we’re getting there…

4. Transgenic Organisms  Transgenic organism: an organism that has DNA from another species put inside of it by scientists  Trans-: across  -Genic: gene  Key Point #1:  Scientists use restriction enzymes to create transgenic organisms

5. Restriction Enzymes  Restriction enzymes cut out the gene from one organism, so it can be placed into another CGAATGGGCCCAATTCTC GCTTACCCGGGTTAAGAG CCCAATTCTC GGGTTAAGAG

6. GloFish!

7. Ditteaux!

8. Adult Stem Cells  In Louisiana, it is ILLEGAL to create embryonic stem cells  So all local research is done using adult stem cells  New Orleans  Mandeville!?

9. While You Are Waiting…  Write a letter to the editor of the New Orleans Times-Picayune  Identify applications of stem cell research  Explain your position on stem cell research Is embryonic stem cell research morally acceptable? Is adult stem cell research morally acceptable? Why or why not?

10. Exit Question  Next week, we will study cloning.  Please tell me everything you already know about cloning.  Please tell me everything you don’t know but want to find out about cloning.
