Genetically engineered organisms (GEOs) are biological entities—prokaryotic or eukaryotic—whose genomes have been deliberately modified using recombinant DNA technologies, genome editing tools (e.g., CRISPR-Cas systems, TALENs, ZFNs), or transgenic methods to introduce, delete, or alter specific genetic sequences. This topic encompasses the design, construction, and characterization of modified genomes; vector systems and delivery methods; control of gene expression; and assessment of phenotypic consequences, stability, and off-target effects. It also includes applications in basic research, biotechnology, agriculture, biopharmaceutical production, and synthetic biology, as well as associated biosafety, containment, and regulatory frameworks governing experimental and environmental use.
Chicken eggs are already used to harvest helpful proteins called antibodies to protect humans from viruses such as influenza. Now, a breakthrough at the University of Missouri could one day lead to chickens that produce other ...
