Selective BreedingControlling 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, flavr savr tomato

More GMOsCows engineered to produce HGH (Human Growth Hormone)Nitrogen producing plants-decreased need for fertilizer

ControversyIs it safe?Antibiotic resistanceNatural populations/ecosystemGenetic modification of animals & humans

Spiders + goatsCanadian scientists combined spider DNA with the cells of lactating goats, they produced silk with their milk

Thats weird right?

ProsGrowing replacement organs for organ transplantsPreventing diseaseMedical research: simulating human diseasesGene TherapyIntroducing a healthy gene to replace a diseased gene in a human being.Viral vector

Gene Therapy for Cystic Fibrosis

Jesse GelsingerVolunteered for experimental gene therapy in 199918 yrs oldDied a few days after from massive reaction to viruses


How is it done?

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?
