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 remarkable quality of bioengineering is that scientists can take biological processes honed by millions of years of evolution and use them to efficiently create drugs, chemicals and other products to improve our lives. ...

Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when mRNA guides protein assembly.
