Genetic applications Genetic applications Presentation Transcript

  • Genetic Applications By Rabbi G.
  • Vocabulary
    • ____________- any change in the base sequence of an organism DNA
    • ____________- Process of making a group of genetically identical offspring from the cells of an organism
    • _____________- transfer of gentic information from one organism to another
  • Genetic research
    • Is the fastest growing fields in science
      • Two very common areas if genetic research are
        • Cloning
        • Genetic Engineering

  • Cloning
    • Process of making a group of genetically identical offspring from the cells of an original organism
    • This is great in agriculture
      • Plants with great qualities can be produced over and over gain from one plant

  • Cloning II
    • We have cloned animals also (very early stages of research)
      • Dolly tehsheep was the first succeful adult animal clone
      • They clone from the fetal ( baby in womb) cells
  • Genetic Engineering
    • Genetic information being passed from one organism to another
      • This forms recombinant DNA ( re combine)
      • New genes can be transferred to the organism through this process
  • Genetic Engineering II
    • It has been very successful in taking humans genes and transferring them into certain bacteria
      • They then let the bacteria grow and then treat certain disorders such as
        • HGH – helps with height
        • Insulin – Diabetes etc..
      • Eventually, they hope to cure many more disabilities through this process
  • Selective Breeding
    • There are ways that scientist can improve, produce, and maintain new varieties of animals and plants
      • AKA
        • Artificial selection
          • Inbreeding
          • Hybridization
          • Vegetative propagation
  • Inbreeding
    • Is mating ( getting together) two closely related individuals
      • This method is used to make sure that the off spring are homozygous ( have the same genotypes) for most traits
    • The drawback to interbreeding is the fact the organisms are so closely related some rare recessive traits to come out.
      • Therefore people who interbreed do not continue with organisms that have shown these recessive traits.
  • Hybridization
    • As we stated before selective breeding of plants is very common to get eth best plants and cops possible.
      • Farmers would take two similar crops ( one with great fruit and other with other great) traits and put them together
      • The plant or fruit would have a greater market value
    • When two closely related species are crossed the off spring are called hybrids
