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
