Study Notes

Introduction to Genetic Engineering

  • Genetic engineering, also known as genetic modification, is a technique that alters an organism's DNA to achieve desired traits or eliminate unwanted ones.
  • The term "genetic engineering" was coined by Nikolay Timofeev-Ressovsky in 1934.
  • The first genetically modified organism (GMO) was a bacterium generated by Herbert Boyer and Stanley Cohen in 1973.
  • Jack Williamson used the term in his 1951 novel, Dragon's Island.

Applications of Genetic Engineering

Applications in Medicine

  • Gene Therapy: A technique to treat genetic diseases.
  • Drug Production: Creating medicines like insulin, growth hormones, vaccines, monoclonal antibodies, heparins, and allergy medications using genetically modified organisms.
  • Disease Diagnosis: Using genetic testing to identify disease-causing mutations, helping diagnose conditions that might otherwise be misdiagnosed.

Agricultural Applications

  • Improved Crop Yields: Producing crops with enhanced traits for higher yields.
  • Sustainable Agriculture: Improving resource efficiency and reducing reliance on pesticides.
  • Animal Biotechnology: Using genetic engineering to increase animal productivity, improve product quality, and reduce environmental impact.
    • Example: Chicken size increasing
  • Enhanced Nutritional Value: Modifying crops to boost their nutritional value, like beta-carotene in golden rice.

Industrial Applications
