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.
Leading synthetic biologists have shared hard-won lessons from their decade-long quest to build the world's first synthetic eukaryotic genome in a Nature Biotechnology paper. Their insights could accelerate development of ...
