Transposition

The transposition of a transposable element to a new location without it being lost from the original location.

Transposition
Moving a DNA segment from one position of the genome to another or to a different genome. This change in genome structure happens in many organisms from bacteria to higher plants and animals.

Transposition is coupled to replication by the DNA synthesis-methylation cycle acting at two sites: the promoter for transposase and the DNA target site of the transposase.
Copy number control is exercised by the level of the outward transcript.

Transpositional recombination
Another form of site-specific recombination, transpositional recombination does not require an identical strand of DNA in the mobile element to match with the target DNA.

Transposition in these cases occurs by a "copy (command/control-C) and paste (command/control-V)" mechanism. This requires an additional enzyme — a resolvase — that is also encoded in the transposon itself.

Transposition
The movement of a discrete segment of DNA from one location in the genome to another.

Transposition: The movement of DNA from one location to another location on the same molecule, or a different molecule within a cell.

Another is transposition. This is when a stretch of DNA simply excises itself from one part of genome and moves itself to another. Transposons are pieces of DNA that do this.

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.

Free transposons are not found; they spread via transposition into mobile DNA molecules such as plasmids.

In vitro transposition was used to introduce a selectable marker as well as a plasmid replicon that is functional in E. coli.

They mostly come in as chunks of DNA by so-called "transposition" or in some cases "retro transposition" from autosomes. These events have brought to the Y chromosome new genes that appear to be critical for spermagenesis.

A mobile piece of DNA that is flanked by terminal repeat sequences and typically bears genes coding for transposition functions. See transposable genetic element.
Full article >>>

The simplest kind of a transposon, consisting of inserted repeats of DNA flanking a gene for transposase, the enzyme that catalyzes transposition.

Transposition. The movement of a DNA segment within the genome of an organism. Transposon (transposable, or movable genetic element). A relatively small DNA segment that has the ability to move from one chromosomal position to another.
