Run-down for Genetic Modification/ Enhancement (aka “Gene Splicing”)

 

spideyManipulation of Genes outside of the normal reproductive process

Isolate, manipulate, reintroduce DNA so as to express different protein production

 

  1. Create new physical/ physiological characteristics (pest-resistant crops)
  2. Introduce novel trait (luciferase into tobacco plants)
  3. Produce wholly new proteins (intentional “mutation”)

Process: Segment of DNA " DNA is made up of a number of chromosomes " some set of chromosomes is a gene

 

  1. Genes can code for
    1. production of a particular protein
    2. gene regulation
    3. gene expression

 

  1. Uses
    1. Animals: produce “chimera,” (glow fish, Spiderman)

                                        a.    goals similar to animal husbandry

    1. Plants: produce radical hybrids  (Franken-food)

                                        a.    Tomatoes, corn, soybeans, rice

  1. Biodiversity Concerns

 

  1. Intellectual Property Concerns

 

The double-helix structure of DNA allows modification of plasmids to take place.
  1. Health Concerns:

                        a.    Potatoes modified with snowdrop: stunted growth and destroyed immune system of test animals

                        b.    Corn: Kidney failure

                        c.    Unknown allergens
