Chapter 13 Genetic EngineeringSection 13-4 Applications of Genetic Engineering

2

Transgenic OrganismsThe Genetic Principles Are Universal For All Life Forms: Based On DNA All DNA Uses The Same Base Sequences Adenine Thymine Guanine Cyctosine Genes Can Be Transferred Between Species Transgenic Organisms

3

Transgenic OrganismsWith The Newly Developed Technologies, Genes Can Be Transferred Between Species. An Organism Which Has Received The Gene of Another species is called a: Transgenic Organism

4

Transgenic OrganismsKey Concept: Genetic Engineering Has Spurred The Growth Of Biotechnology, A New Industry That Is Changing The Way We Interact With The Living World

5

Transgenic MicroorganismsReproduce Rapidly Easy To Grow Used To Produce Human Insulin Growth Hormone Clotting Factors

6

Transgenic AnimalsMice with Human Immune Cells To Study Effects Of Disease Food Animals with Extra Genes For Growth Hormone So The Grow Faster Cows Fish Pigs for Organ Transplants

7

Transgenic AnimalsChickens Resistant To Salmonella & Shigella Animals That Produce Human Proteins In Their Milk

8

Transgenic PlantsGM Plants Are Already In US Food Supply 52% Soy Beans 25% Corn Typical Modifications Bt Genes To Lower Pesticides Resistance To Weed Killers

9

Transgenic PlantsFuture Plant Projects: Plants That Grow Human Antibodies Plants That Grow Plastic Plants With Added Vitamins Golden Rice

CloningCloning Is The Process Of Using A Donor Cell From An Adult Organism To Grow A New Individual Genetically Identical To The Organism From Which The Donor Cell Was Taken

CloningIan Wilmut, Scotland, 1997 Cloned A Sheep – Dolly

12

Cloning – The ProcessStep 1: Donor Cell Taken From Animal To Be ClonedDonor NucleusCan Be Any Diploid Cell With A Nucleus

13

Cloning – The ProcessStep 2: Donor Egg Taken From Another Animal Of The Same Species – This Nucleus Will Be Removed and DiscardedDonor EGG Cell

14

Cloning – The ProcessStep 3: Donor Egg Cell With The Nucleus Removed Is Fused With The Donor Cell Containing The Nucleus From The Animal To Be ClonedDonor Egg with Nucleus RemovedSlight Electric Current

15

Cloning – The ProcessStep 4: In Vitro Development Create Blastocyst From Cloned Donor NucleusIf Fused Cell Begins Replicating It Will Be Placed In Tissue Culture Until It Becomes A Blastocyst.Blastocyst
