1. Catalyst 1.What is a clone? 2.What kind of animals do you know have been cloned? 3.What are some ways that you know of where science influences a living thing (food, animals, humans, etc)?

2. Announcements Homework packet due Friday Progress reports come out today during 7 th period Peer Health Door policy Homework raffle Late work due date Extra credit

3. DNA Technology Introduction to Genetic Engineering

4. DateUnit # and Name: Page # 02/26/2014Unit 3 : Genetic Engineering

5. Objective I will be able to describe how genetic engineering is used to produce biomedical and agricultural products.

6. What is biotechnology? Biotechnology: the manipulation of organisms or their components to make useful products Scientists can modify specific genes and move them between organisms as distinct as bacteria, plants, and animals! Check this out…

7. Glowing Mice!

9. Glowing pigs!

10. Want a glowing pet fish?

11. How about glowing tobacco?

12. Should we make glow in the dark people?!

13. Mighty mouse gene! How might this be useful?

14. Mighty cows = more meat!

15. How about giant vegetables?

16. Basket ball size tomato?

17. Watermelon anyone?

18. Featherless Chickens…

19. Flavr Savr Tomato The FLAVR SAVR tomato was the first genetically engineered crop product to be commercialized. Tomatoes didn’t spoil because the gene for the “fruit softening” protein was altered.

21. What is Genetic Engineering? Genetic Engineering: Manipulating organisms genes for practical purposes –Changes the organisms DNA and gives it new traits –Also known as: genetic manipulation

22. What is genetic engineering used for? Two main purposes: 1. Creating new biomedical products 2. Creating new agricultural products

23. Biomedical Products Using living things and biological processes in connection with medicine Examples: –Creating insulin to help people with diabetes –Human growth hormone: treats stunted growth –Anti-clotting factors to help heart attack patients

24. Mouse growing human ear cartilage! 1997. The mouse had been implanted with a tumor of human cartilage and a form had been placed over the back so that the tumor would grow into the shape of an ear. While the mouse wasn’t genetically engineered to make a human ear, the production of the cartilage tumor cells involved genetic engineering.

25. Agricultural Products Using biotechnology in connection with growing and producing food (plants and animals) Examples: –Pest-resistant crops –Non-spoiling fruits and vegetables –Peanuts that don’t trigger allergies –“Meatier chickens” combined with egg-laying chickens

26. Spider silk producing goats?! This baby goat will produce milk that contains spider silk proteins… a tough, flexible material that could be could be used for a vast array of products, –from artificial ligaments to super-strong replacement tendons or even body armor

27. How do they make these products? Review: Gene = a section of DNA that codes for a physical trait If a gene produces a trait, we can use technology to isolate the gene and insert it into another organism – Example: Gene for weight was inserted into mice in order to study obesity!

28. CFU #1 Genetic engineering has produced chickens whose eggs contains proteins that can be used as medicines. This effect was produced by: A mixing foreign genes into the eggs B injecting foreign genes into the chicken’s reproductive organs C inserting foreign genes into fertilized chicken eggs D genetically changing the nutritional needs of the chicken’s offspring

29. What is the result? Recombinant DNA: DNA in which genes from two different sources, often different species, are combined in one organism

31. What are some other uses for biotechnology? Diagnosis of Diseases Gene Therapy Pharmaceutical Products Forensics: DNA Fingerprinting Cloning And more!!!!

32. CFU #2 The bacterium Agrobacterium tumefaciens infects plants, and a portion of its DNA is inserted into the plant’s chromosomes. This causes the plant to produce gall cells, which manufacture amino acids that the bacterium uses as food. This process is a natural example of: A polyploidy B genetic manipulation C grafting D hybridization

34. Mini Quiz

35. Do Now 3. Give a shout out to one classmate for doing something great this week! 1. Genetic engineering typically involves: A Carefully studying the lungs of the organism B Changing the genes of an organism by inserting foreign DNA into the organism C Mating the organism to another species to produce a new species D Creating mutations in the organism 2. Genetic engineering has produced goats whose milk contains proteins that can be used as medicines. This effect was produced by: A mixing foreign genes into the milk B injecting foreign genes into the goats’ udders C inserting foreign genes into fertilized goat eggs D genetically modifying the nutritional needs of the goats’ offspring
