[transpos(ition) + -on.]transposon (trænsˈpəʊzɒn) n (Genetics) genetics a genetic element that can move from one site in a chromosome to another site in the same or a different chromosome and thus alter the genetic constitution of the organism[C20: from transpos(e) + -on]trans•po•son (trænsˈpoʊ zɒn)
n. a gene or set of genes capable of inserting copies of itself into other DNA sites within the same cell. Also called jumping gene.

transposon[¦tranz′pō‚zän] (genetics) A genetic element which comprises large discrete segments of deoxyribonucleic acid and is capable of moving from one chromosomal site to another in the same organism or in a different organism. transposonenUK
transposon [tranz-po´zon] a discrete DNA sequence that transposes blocks of genetic material back and forth within a bacterial cell from the chromosome to plasmids or bacteriophage particles, by which the material may be transferred to another cell. Transposons frequently carry genes for resistance to antibiotics.trans·po·son (tranz-pō'son), A segment of DNA (for example, an R-factor gene) that has a repeat of an insertion sequence element at each end that can migrate from one plasmid to another within the same bacterium, to a bacterial chromosome, or to a bacteriophage; the mechanism of transposition seems to be independent of the host's usual recombination mechanism. See: jumping gene, transposable element. [L. transpono, pp. transpositum, to transfer, + -on] transposon (trăns-pō′zŏn)n. A segment of DNA that is capable of moving into a new position within the same or another chromosome or plasmid. Also called jumping gene.trans·po·son (trans-pō'zon) A segment of DNA that has a repeat of an insertion sequence element at each end that can migrate from one plasmid to another within the same bacterium, to a bacterial chromosome, or to a bacteriophage. [L. transpono, pp. transpositum, to transfer, + -on]transposon a TRANSPOSABLE GENETIC ELEMENT that often contains genes in addition to those required for transposition, such as antibiotic-resistance genes. There are two main classes in prokaryotes: compound or composite, having copies of an INSERTION SEQUENCE at each end; and complex, having terminal INVERTED REPEAT sequences (generally about 30bp) but no known insertion sequences.AcronymsSeetree nuttransposonenUK
