    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
