Genetic modification

  1. 1. Genetic Modification
  2. 2. GENETICALLY MODIFIED ORGANISMS BY: Nombuso Siphiwe Khumalo For Grade: 12
  3. 3. Introduction It is important that people know more about Genetic Modification (GM), so we will show you. You will know what is GM, who started with the experiences, the advantages and disadvantages, some curious facts, examples of animals and food that have been genetically modified, the countries that produce more GM food and a statistic about the opinion of Romanians people about it.
  4. 4. • Genetic engineering, also called genetic modification, is a process in which genetic material is changed to make possible the production of new substances or new functions to animals, plants or humans using biotechnology. For example, the crops can be resistant to cold, pesticides and diseases. Or eliminate human hereditary diseases and change their physical characteristics.
  5. 5. Gregor Mendel • Gregor Mendel (1822-1884) was born in an Australian Empire and he was a scientist who gained fame as the founder of the new science of genetics. He made experiences with plants variation, implanting genes of one organism to another starting the genetic modification process.
  6. 6. Advantages of GMO • Advantages: 1. Modified to make them more resistant to unfavorable conditions 2. Produce higher yields 3. Use less fertilizers 4. Use lesser water 5. Pest resistance 6. Herbicide tolerance 7. Increasing food supplies in corelation with an increasing world population.
  7. 7. Disadvantages Harmful to environment Harmful to humans Give rise to 'super weeds‘ Super weeds' dominate the fields and affect main crops • Genes from the genetically modified food could be transferred to the pests which can make them become resistant to the pesticides and the pesticides become useless. • • • •
  8. 8. Facts • Many people lie about the effects of GM many times because of economical interest. But here are some true facts: • The mutilation can lead to many unexpected changes like poor crop performance, alteration in the nutritional content, toxic and allergenic effects. • It doesn’t reduce pesticide, it even increase. • It doesn’t increase crop field potential but it makes it worst by destroying the needing soil nutrients. • Creates serious environmental problems, killing important animals. • It doesn’t help solve climate change because of the increase of chemicals • It won’t help to end up with the world hunger, the food is just badly distributed.
  9. 9. Genetic modification in animals Glow-in-the-dark cats in South Korea The Environing, is a pig more environmentally friendly by decreasing the phosphorous.
  10. 10. • COWS PRODUCE HYPOALLERGENIC MILK • In New Zealand, the cow produces milk almost entirely free of a protein which causes allergies. And the bigger size of the cow that provides more meat. GLOW DARK PIGS Scientists of Taiwan, created three pigs that glow in the dark. Their objective was use the glow dark pigs to study the combat of human diseases.

  12. 12. What is GM food? • Genetically Modified (GM) foods are produced from genetically modified organisms (GMO) which have had their genome altered through genetic engineering techniques. The genes of plants can be modified to make them more resistant to unfavorable growing conditions and also to produce higher yields with the use of lesser fertilizers and water. Involving genetically modified organisms (GMO) which are potential environmental hazards. Examples of this GM food are; soybean, corn, canola and cotton seed oil.

  14. 14. The banana vaccine – To fight against diseases such as cholera and hepatitis. Salmon that grows faster – To feed more population and its good by its properties. Bigger, longer-lasting tomatoes - These are engineered to produce tomatoes that can remain fresh for longer and be bigger. Cows that fart less - They have been produced to fight the deleterious effects that cow flatulence can have on the environment.
  15. 15. Conclusion Now you know more about this procedure. The main creator of GM was Gregor Mendel in the XIX century. And we could see the good things about this modern tecnique, but there are also lots of problems that could rise because of this. America is the continent that produces more GM food. And you can be eating a lot of it without even knowing though most of the people doesn’t agree with GMO’s.
