Genetic engineering[1]

  1. 1. Genetic Engineering BY: Sophia Rojas Period:1
  3. 3. The Basics Principals: Genes <ul><li>What are genes ? </li></ul><ul><li>Segments of DNA </li></ul><ul><li>Found on the chromosomes of an organism inside the nucleus (There are 43 chromosomes,23 pairs) </li></ul><ul><li>They are directions for protein build up. </li></ul>
  4. 4. The Basic Principals: Heredity <ul><li>What is Heredity ? </li></ul><ul><li>Heredity traits determined by specific genes. </li></ul><ul><li>Organisms inherit genes in pairs, one gene from each parent </li></ul><ul><li>These hereditary traits include the dominant and recessive traits </li></ul>
  5. 5. The Basic Principals: Alleles <ul><li>There are two types of alleles, recessive and dominant </li></ul><ul><li>The combination of these determines which traits show and which don't </li></ul><ul><li>The process by which alleles are transmitted was discovered by Gregor Mendel </li></ul>
  6. 6. The Human Genome Project: <ul><li>A Thirteen year project coordinated by the U.S of Health. </li></ul><ul><li>Project goal was to identify about 30,00-35,000 genes in a human body. To make accessible for study. </li></ul><ul><li>Discovered there are about 35000 in a human DNA molecule. </li></ul><ul><li>Results include genetic cloning of Dolly the sheep. </li></ul>
  7. 7. The Humans Genome Project <ul><li>Ethical issues that which occurred were the enhancement engineering attempts extend traits or capacities beyond their normal levels </li></ul><ul><li>Enhancing one part of the body could cause stress on other parts </li></ul>
  9. 9. What is a genetic disorder? <ul><li>A disease caused from a mutation in a DNA or an entire chromosome. </li></ul><ul><li>There are three types of genetic disorders- </li></ul><ul><li>single gene disorder- caused by defects in one particular gene </li></ul><ul><li>chromosome abnormalities - a structural abnormality in one or more chromosomes. </li></ul><ul><li>multifactor disorders - mutations in multiple genes which can b triggered by ones surroundings </li></ul>
  10. 10. Genetic Disorders <ul><li>A karyotypes is a picture of a persons chromosomes to help look for missing or extra chromosomes. </li></ul><ul><li>Genetic counseling is used o help parents who carry a genetic disorder find the possibility their offspring will have it as well </li></ul>
  11. 11. All About Genetic Engineering
  12. 12. What is this? <ul><li>Genetic material transferred into another embryo to tweak its genetic makeup and physical appearance such as disorders, eye color, or skin tone </li></ul><ul><li>This process is carried out in five steps: </li></ul><ul><li>-Gene of interest is isolated </li></ul><ul><li>- Transfer vector is inserted into the genes </li></ul>
  13. 13. Opinions on genetic engineering
  14. 14. PROS CONS <ul><li>Better nutritional qualities and increased yield in vegetables. </li></ul><ul><li>Engineering seed could become resistant to pest. </li></ul><ul><li>Genetic modification of foods can be used to increase their medicinal value. </li></ul><ul><li>Enhance positive human traits. </li></ul><ul><li>Gene therapy can lead to mutation effects. </li></ul><ul><li>Very uncommon because of the expenses. </li></ul>
  15. 15. Views on Genetic Engineering <ul><li>Ron Epstein at the State University believes god made he world in his image and it should stay like that “The human race is created in God's image.” </li></ul><ul><li>The Methodist Church's opinion has stuck with and supported scientific remedies for certain genetic diseases however believe study should be restricted. </li></ul>
  16. 16. Views on Genetic Engineering <ul><li>I am not for genetic engineering in humans nor Plants and animals because later on it may have a large impact on us, inside and out. For example animals with hormones can affect human health while chemicals for plants can affect our insides and breathing as well. </li></ul><ul><li>WHATS YOUR OPINION? </li></ul>
  17. 17. Citation <ul><li>Primary </li></ul><ul><li>http:// /content/alth/ng s / </li></ul><ul><li> </li></ul><ul><li>Secondary </li></ul><ul><li>http:// / </li></ul><ul><li> </li></ul>
