Genetic Engineering GMOs, Selective Breeding, Gene Therapy, Cloning
Selective Breeding • Controlling the way organisms breed for desired traits
Genetically Modified Organisms (GMOs) • An organism whose genetic make-up has been somehow modified by humans for our benefit. • Bt plants: insecticide, golden rice, flavrsavr tomato
More GMOs • Cows engineered to produce HGH (Human Growth Hormone) • Nitrogen producing plants-decreased need for fertilizer
Controversy • Is it safe? • Antibiotic resistance • Natural populations/ecosystem • Genetic modification of animals & humans
Spiders + goats… • Canadian scientists combined spider DNA with the cells of lactating goats, they produced silk with their milk • That’s weird right?
Pros • Growing replacement organs for organ transplants • Preventing disease • Medical research: simulating human diseases
Gene Therapy • Introducing a healthy gene to replace a diseased gene in a human being. • Viral vector
Jesse Gelsinger • Volunteered for experimental gene therapy in 1999 • 18 yrs old • Died a few days after from massive reaction to viruses
What is wrong and what is right? • Ethics, where do we draw the line? Do we draw the line? • Is it safe? • GMOs disrupting the balance of nature? • I Am Legend Zombies?
