  1. Genetically Modified Organisms (GMOs) And how they are important in the 21st century By: SB

  2. What Are GMOs? • GMOs are organisms who have had their genetic makeup altered to give them new characteristics or traits. • Can be used to greatly improve all types of organisms • Bacterial Cells • Plants • Animals • Humans

  3. How They’re Created • Desired gene is isolated and cut with restriction enzymes • Replicated many times through PCR or bacterial plasmids. • 2 ways of getting the gene into the cell… - A vector (bacterial plasmids or viruses) - Shotgun method (bio-ballistics) • Done in the embryonic stem cells. • 2 types of genetic engineering - Positive eugenics - Negative eugenics

  5. GM Bacterial Cells • Antibiotic resistant bacteria made to help find new drugs • Human genes added to bacteria to produce human hormones that can treat certain diseases or disorders. • Certain bacteria can be used to benefit our environment.

  6. Genetically Modified Plants • Enhances the taste and quality of fruits, vegetables, grains, etc. • Takes less time to ripen and stays ripe longer • Greater resistance to disease, insects and herbicides • Increases the yield of the crop

  10. Genetically Modified Animals Agriculture • Better yield of meat, eggs and milk • Increased resistance, hardiness and productivity Pharming • Certain animals produce substances that are useful in treating human patients Medical Research • Helps to determine what certain genes do • Experiments done on animals with human diseases allow for discoveries of new drugs

  11. Genetically Modified Humans • Eradicates all genetic diseases. • All physical traits of a person can be modified to be what the parents wish. • It’s believed that psychological and social characteristics can be altered as well. • Improve health and lifespan.

  12. Pertinence in the 21st Century • The use of genetically modified crops and animals to help solve world hunger problems • Using genetically modified bacteria or animals in the field of medical research to find or develop new drugs • Genetic engineering of humans to eradicate genetic diseases • Germline manipulation of humans to produce “designer babies”
