Study Notes
Genetic Engineering
- Definition: The manipulation of an organism's DNA to introduce new traits or characteristics
- Techniques:
- Isolation of DNA from cells
- Cutting and joining DNA molecules using restriction enzymes and ligases
- Insertion of foreign DNA into a host organism using vectors (e.g. plasmids, viruses)
- Applications:
- Production of recombinant proteins (e.g. insulin, vaccines)
- Development of genetically modified crops (e.g. pest-resistant, drought-tolerant)
- Gene therapy for genetic disorders
Recombinant DNA
- Definition: A DNA molecule that combines genetic material from multiple sources
- Formation:
- Cutting DNA molecules using restriction enzymes
- Joining DNA fragments using ligases
- Importance:
- Allows for the creation of new genetic combinations not possible through natural breeding
- Enables the production of recombinant proteins and bioproducts
Bioproducts
- Definition: Products derived from biological sources, such as cells, tissues, or organisms
- Examples:
- Recombinant proteins (e.g. insulin, growth hormone)
- Vaccines
- Antibodies
- Enzymes
- Biofuels
- Applications:
- Pharmaceutical industry
- Agricultural industry
- Environmental remediation
Bioprocessing
- Definition: The use of biological systems or living organisms to develop products or services
- Steps:
- Upstream processing: cell growth, fermentation, and harvesting
- Downstream processing: purification, separation, and formulation
- Applications:
- Production of bioproducts
- Bioremediation
- Biocatalysis
Regulatory Frameworks
- Importance:
- Ensuring the safe and ethical development of biotechnology products
- Protecting the environment and human health
- Examples of regulatory agencies:
- US Food and Drug Administration (FDA)
- US Environmental Protection Agency (EPA)
- European Medicines Agency (EMA)
- Regulations:
- Guidelines for genetic modification and gene editing
- Safety protocols for handling and disposal of biotechnology materials
- Labeling and traceability requirements for bioproducts
