Presentation Transcript

  1. DNA Technology • Terminology • USES of DNA technology • DNA fingerprinting • protein production • gene therapy • GMO - Genetically Modified Organisms • cloning • Stem Cells • Genetic Counseling

  2. DNA Technology - Terminology: • Restriction Enzyme • cut DNA in specific spots depending on the code in the enzyme • Bacterial Vectors • Bacteria used to carry pieces of genetic information from other organisms • plasmids – ring shaped DNA • Recombinant DNA • Bacterial plasmid and inserted gene

  3. Genetic Counseling: • Genes for particular disorders are known • may be markers than can be tested for • determine probability of • Huntington’s Disease • If one parent has a copy of the gene 50% chance for offspring • If both parents have a copy 75% • Breast Cancer • BRAC1 and BRAC2 gene

  4. Genetic Testing // IVF Genetic Screening • pedigree analysis or direct genetic testing available for Cystic Fibrosis • parents with a family history of Cystic Fibrosis can screen embryos for the disorder PRIOR to in vitrofertilization • fertilization occurs • single cell removed • embryos • first child as the result of this screening born in 1990
