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.
Gas vesicles are among the largest known protein nanostructures produced and assembled inside microbial cells. These hollow, air-filled cylindrical nanostructures found in certain aquatic microbes have drawn increasing interest ...

Twisting upwardly on trees and other plants—along with houses and even lampposts—vines are a wonder of nature. However, their marvels mask their parasitic behavior: in attaching to other life forms, vines block sunlight necessary ...

DNA can be thought of as a vast library that stores all genetic information. Cells do not use this information all at once. Instead, they copy only the necessary parts into RNA, which is then used to produce proteins—the ...
