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.
Industrial oxidation chemistry is a cornerstone of modern manufacturing, accounting for nearly one-third of all chemical industrial processes. While essential for making pharmaceuticals, dyes, and many specialty chemicals, ...

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.
