Study Notes

Gene Therapy

  • Extracting white blood cells and introducing a missing gene (ADA) was crucial in a gene therapy procedure.
  • Gene therapy can treat genetic disorders.

GMO Applications

  • Golden Rice produces beta-carotene (a vitamin A precursor) to combat vitamin A deficiency.
  • Humulin is a GMO used to produce human insulin for diabetes.
  • Poplar trees are genetically modified to enhance paper production.
  • Shrub tobacco is used in bioremediation to remove harmful substances from polluted air.
  • Periwinkle plants are used in pharmaceuticals due to their alkaloids with therapeutic properties.
  • AquaAdvantage Salmon grow year-round.

Cloning

  • Dolly was the first mammal cloned from an adult somatic cell.
  • Cloning creates genetically identical organisms through asexual reproduction.

Genetic Disorders

  • Severe Combined Immunodeficiency (SCID) significantly weakens the immune system.
  • Down syndrome is caused by an extra chromosome 21.

Genetically Modified Foods

  • Arctic Apples resist browning/discoloration.
  • Blue roses produce a blue hue through pigment-producing genes.
  • Fortification enhances staple foods with nutrients (e.g., beta-carotene in rice for vitamin A).

Bioremediation

  • Genetically modified plants, like shrub tobacco, clean polluted areas by absorbing and detoxifying harmful substances.

Other Concepts

  • Memento Mori: a Latin phrase meaning "Remember you will die," a reminder of mortality.
  • Steve Wozniak: co-founder of Apple Inc. who developed the Apple I computer.
  • Hedonism: the philosophy that focuses on "Eat, drink, and be merry for tomorrow we die."
  • Electronic Brains: the term for the first generation of personal computers in the 1970s.
