transposon
(redirected from Transposable genetic element)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.03 sec.
transposon /trans·po·son/ (trans-po´zon) a small mobile genetic (DNA) element that moves around the genome or to other genomes within the same cell, usually by copying itself to a second site but sometimes by splicing itself out of its original site and inserting in a new location. Eukaryotic transposons are sometimes called transposable elements.
trans·po·son (trns-pzn)
n.
A segment of DNA having a repeat of an insertion sequence element at each end as well as genes specific to some other activity such as resistance to antibiotics; it is capable of migrating to a new position within the same or another chromosome, plasmid, or cell and thereby transferring genetic properties.

transposon
[transpō′sən]
Etymology: L, transponere + on
a segment of DNA that can move from one place to another in a cell's genome or between a bacterial cell and a plasmid or virus. Viruses may even carry a transposon from one bacterium to another. Also called jumping gene, transposable element.

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.
