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

Microorganism Transformation: Using genetic engineering to modify microbes to produce valuable substances or assist in industrial processes.
Bioremediation: Utilizing genetically engineered organisms to clean up environmental pollutants.
Biodegradable Plastics: Developing biodegradable plastics from biological sources.
Industrial Enzymes: Creating enzymes with desired properties for industrial applications, like food production or textiles.
