Genetic modification Genetic modification Presentation Transcript

  • Genetic Modification
    By James Hennessy and
    Liam Carey
    Mrs. Martinez
  • Basic Principles of Genetics.
    If there is a dominant and a recessive gene the dominant gene will always show when present.
    All organisms heredity is one trait from each parent.
    Traits are passed down from one generation to the next.
  • Human Genome Project
    An international study of the entire human genetic material
    You can see if you have a predisposition to things like alcoholism or dementia by seeing agene therapist who will tell you your gene sequence and Karyotypes.
    It began in 1990 and ended in April 3rd 2003.
    Stores this information in databases, identify all the approximately 20,000-25,000 genes in human DNA,
  • Genetic Disorders
    Caused by mutations or changes in the persons DNA.
    It may be caused by being exposed to radiation or it may just be caused by your DNA
    These are not the same as chromosome related traits like down syndrome, they are genetically passed down through alleles and cause diseases like Alzheimer's or dementia.
  • Why are Genetic modifications in foods good for us?
    Golden rice is genetically modified to grow with little soil and a lot of water. This is good for countries with very much rainfall of course.
    GM products can include medicines, vaccines, and food ingredients.
    GM has created potatoes invulnerable to virus’s and rice with increased vitamins.
  • Other Pro’s of Genetic Modification in Food.
    • Dr. C. S. Prakash tells about how Biotechnology “would allow hybrid rice to be colonized by bacteria that fix nitrogen from the atmosphere.”
    • Also he wanted to genetically modify the crops so that he could keep them away from weather, pests, and plant disease.
    • GM crops can be used to increase their medicinal value, making homegrown edible vaccines.
  • Con’s of GM Engineering in crops.
    GM crops may create “super weeds” that could be harmful to other crops.
    Human gene therapy could have troubling side effects.
    GM Engineering may hamper diversity in humans which could hamper cloning.
    GM engineering may cause genetic illness in people’s DNA causing problems in their heredity.
  • More cons.
    If pedigree GM crops create hybrid crops with other plants than the new plants could have unknown abilities.
    A superweed could destroy the ecosystem.
    Some unusual gene expression may cause a allergic reaction in consumers.
  • Conclusion
    In conclusion I learned that some people like the idea of having genetically modified foods that will help especially in poor countries, and other people do not want modified foods because of ethic or nutrients problems in the crop and would rather have foods that are grow with no injections.
    What do you think?
    I think that America should stop genetic modification of foods unless it is necessary.
