Study Notes
Genetic Engineering
- Definition: Genetic engineering is the manipulation of an organism's genetic material to introduce new traits or characteristics.
- Techniques:
- Recombinant DNA technology: combining DNA from different organisms to create a new DNA molecule.
- Gene editing: using enzymes to make precise changes to an organism's DNA.
- Gene cloning: creating multiple copies of a gene.
- Goals:
- To introduce desirable traits, such as pest resistance or drought tolerance.
- To improve nutritional content or shelf life.
- To produce novel products, such as biofuels or pharmaceuticals.
GMO Foods
- Definition: Genetically modified organisms (GMOs) used as food or ingredients.
- Examples:
- Crops: corn, soybeans, canola, cottonseed.
- Fruits and vegetables: papaya, squash, apples.
- Livestock: genetically modified salmon.
- Benefits:
- Increased crop yields and reduced pesticide use.
- Improved nutritional content, such as vitamin-enhanced "golden rice".
- Enhanced resistance to diseases and pests.
- Controversies:
- Potential environmental impact, such as gene flow or unintended consequences.
- Human health concerns, such as allergic reactions or altered nutritional content.
- Labeling and regulation debates.
Biotechnology
- Definition: The use of biological systems, living organisms, or derivatives to create products, tools, or processes.
- Applications:
- Medicine: genetic testing, gene therapy, and regenerative medicine.
- Agriculture: GMO crops, precision agriculture, and livestock improvement.
- Industry: biofuels, bioproducts, and environmental remediation.
- Tools and techniques:
- Fermentation: using microorganisms to produce chemicals or biofuels.
- Genetic engineering: manipulating DNA to introduce new traits.
- Biomimicry: developing materials or systems inspired by nature.
- Future directions:
- Synthetic biology: designing and constructing new biological systems.
- Gene editing: using CRISPR and other technologies for precision editing.
- Personalized medicine: tailoring treatments to individual genetic profiles.
