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.
A researcher's keen eye and spirit of curiosity led to the discovery of a new method for cell engineering—a finding that opens doors to more sustainable sources for everything from fuel to vitamin supplements.
