Transposons are sequences of DNA that can move around to different positions within the genome of a single cell, a process called transposition. In the process, they can cause mutations and change the amount of DNA in the genome.

Definition of transposon :
A mobile piece of DNA that is flanked by terminal repeat sequences and typically bears genes coding for transposition functions. See transposable genetic element.
Transposon tag
Use of a transposon insertion in a gene to follow the inheritance of the gene.

A transposable genetic element; a mobile segment of DNA that serves as an agent of genetic change.

Transposons have also been described as a sort of wrangler; they can bring multiple resistance genes into a single plasmid. How do they do that?

transposon insertion Transposable elements (transposons) include a diverse class of DNA sequences that are capable of inserting, excising and relocating into chromosomal or extrachromosomal DNA.
Transposon (transposable, or movable genetic element). A relatively small DNA segment that has the ability to move from one chromosomal position to another.
Transposons
Transposons are segments of DNA that are capable of moving to another location, either on the same chromosome or on a different one. If a transposon inserts itself within another gene, it can prevent the gene from expressing itself.
retrotransposon - A transposable DNA element (transposon) which is replicated through an RNA intermediate via reverse transcriptase.
Transposons are DNA fragments incorporated into the chromosomal DNA. Unlike episomes and prophages, transposons contain a gene producing an enzyme that catalyzes insertion of the transposon at a new site.
Transposon (Tn)
DNA elements carrying genes for transposition and other genetic functions. The former genes enable those elements to move from one site on a chromosome to another.

TRANSPOSON - A transposable genetic element; certain sequence elements which are capable of moving from one site to another in a DNA molecule without any requirement for sequence relatedness at the donor and acceptor sites.

transposase --> transposon
(Science: molecular biology) small, mobile dNA sequences that can replicate and insert copies at random sites within chromosomes.
(See Transposon.) mRNA. See Messenger RNA. Multi-locus probe. A probe that hybridizes to a number of different sites in the genome of an organism. (See Probe.) Mutagen. Any agent or process that can cause mutations. See Mutation. Mutation.
Free transposons are not found; they spread via transposition into mobile DNA molecules such as plasmids.
The mechanism by which homothallic yeast cells alternate mating types, involves two silent transposons (cassettes) and a region where these cassettes can be expressed (cassette player).

Insertion sequence A simple DNA transposon, composed of a kilobase sequence that specifies a transposase and is bounded on either end by inverted terminal repeats; an insertion sequence can insert itself into any site on a bacterial chromosome.
