Definitions Gene: transmitting characteristics from one generation to the next. Genetic: science of genes and/or heredity. Genetic Engineering: manipulation of the objects of the natural world to benefit humans. Genetically modified organisms (GMO): an organism with altered genetic material. Biotechnology/ Biotech Foods: the use of biological processes in industrial production.
How is genetic engineering done? DNA from two organisms are combined from single units A,C,G, or T. Genes are brought together from opposite organisms. Cloning takes place. Finding suitable genes through: 1. Genetic makeup of organisms 2. Amino acids genetic code sequence
Risks of Genetic Engineering Dangerous pathogens or diseases Spreading antibiotic resistance microorganisms New species of plants Use of herbicides Possible new diseases
Benefits of Genetic Engineering Versatility New pharmaceuticals Easy to contain Clean up is quick Biodiversity of wildlife Pesticide and herbicide use is lower Food security New GM plants that can tolerate farming without suffering New treatments for cancers and genetic disorders
Conclusions If you are going to eat GM food, do it in moderation. Everything we do should be in moderation. This could be a great supplement to health in the future. The main purpose of GM foods is to try to cut back on herbicide usage and inventing new ways to help with certain treatments.
