mobile genetic element

Accession MOBIO:0000001
DefinitionMobile genetic elements (MGEs) are a type of genetic material, a segment of DNA or RNA, that is capable of movement around a genome or that can be transferred from one species or replicon to another. These include transposons, plasmids, bacteriophages, and genomic islands. The mechanism of movement may be self-encoded or may rely on other enzymes and structures, such as a pilus. In bacteria, MGEs are often associated with the movement of antibiotic resistance genes and virulence factors from one species to another, for example by plasmid-mediated transfer.
