Examples
-
These nimble pieces of genetic material are also known as transposons.
Academic text (1995) -
Transposons also facilitate the transfer of genes that enable the bacteria to become drug-resistant.
Academic text (2000) -
Because they knew the genetic sequence of the transposon, they could find it in the N gene.
Academic text (1995) -
So here there you can see there is an integrase which is part of the transposon facility.
-
The presence of these transposons further facilitates the transfer of resistance genes between bacteria.
Academic text (2000) -
When the plantlets began succumbing to the virus, the researchers figured that the transposon had likely hit the N gene and disabled it.
Academic text (1995) -
When transposons, or "jumping genes," bundle other resistance genes into a plasmid, the recipient microbe becomes equipped with multiple resistances.
Academic text (2000) -
Many intact bacteria contain specialized transposons, termed integrons, that are like flypaper in their propensity for capturing new genes.
Academic text (2000) -
Enterobacteriaceae isolated from both humans and animals in 1983 showed little resistance to nourseothricin, but by 1985, transposon-encoded resistant E. coli were isolated from pigs and meat products.
Academic text (2000) -
Transposons can move from one location to another in the genome, thereby altering the function of nearby transposons.

Etymology
Transposon breaks into trans- meaning 'across' and the same root as position meaning 'place'. So a transposon is a piece of DNA that can move 'across places' inside an organism's DNA, which is why it can insert into genes and change how they work.
