    Study Notes

    Genetically Modified Organisms (GMOs)

    • GMOs are organisms with deliberately altered genetic makeup
    • Microorganisms, insects, plants, fish, and humans can be GMOs
    • In vitro genetic engineering techniques introduce foreign DNA into an organism to create GMOs
    • The donor DNA source is not the GMO itself
    • GMOs can address issues like environmental pollution, food safety, and security

    Intended Learning Outcomes

    • Discuss concepts of GMOs and biotechnology
    • List uses and applications of GMOs (Agriculture, Aquaculture, Food, Biomedical)
    • Analyze economic, social, health and environmental impacts of GMOs
    • Discuss ethical issues of GMOs in coastal environments and biodiversity
    • Understand techniques for creating GMOs

    GMO Introduction

    • GMOs change certain traits by altering the genome (genetic makeup)
    • Editing is precise changes in DNA using enzymes to cut and edit
    • In vitro techniques are involved to incorporate desired DNA
    • This technology, for example, introduces DNA from a daffodil into a carp (auto and allo-transgenic)

    GMO Applications

    • Agriculture: Improved crop yields, lower costs, better nutrient composition, pest and disease resistance, increased food security
    • Aquaculture: Accelerated growth rates, enhanced disease resistance, increased temperature tolerance
    • Food Industry: Food enzymes (FE) used more frequently, increased FE yield through microbial technologies

    GMOs in Biomedical Research

    • Advancement in biological and medical research because GMOs are very crucial for new therapies
    • GMOs are used to understand human genes and their function, leading to better disease treatment (e.g., cancer, Alzheimer's).
    • GMO development of antibodies and medicines

    Ethical Issues and Impacts

    • Concerns over the safety of human consumption
    • Unintended or unpredictable consequences like ecosystem disruption/competition
    • Potential harm to non-target species or their environments from gene spread/toxins
    • Social issues including community displacement and exploitive labor practices related to some GMO products
    • Current debate on use and regulation as a global issue

    Biosafety

    • The Cartagena Protocol on Biosafety (CPB) recognizes the need for biosafety in GE research/development
    • Protocols were adopted in 2003, and aim to set up procedures for safe trans-boundary movements, harmonize risk assessment principles, and establish a clearing house
    • Institutional Biosafety Committees ensure adherence to pertinent regulations for experiments/GMOs
