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.


(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]


(trænsˈpoʊ zɒn)

a gene or set of genes capable of inserting copies of itself into other DNA sites within the same cell. Also called jumping gene.
[1974; transpos (ition) + -on1]

For starters, the genome -- while typical in size -- contains twice as many so-called transposable elements, DNA fragments that can shift position.
Retrotransposons are transposable elements (TE) that generate new copies via an RNA intermediate.
However, some examples of non DNA-sequence based inheritance in mammals, plants and invertebrates are linked to the control of selfish, transposable elements in the genome.
This pattern of activity contrasts with the conventional belief that transposable elements are highly methylated to prevent the potentially harmful effects of mutations on functional genome integrity and maintenance of genomic stability.
However, it is possible that variations have arisen as a result of the loss or gain of primer annealing as a result of point mutation, insertion, deletion or transposable elements (Peschke et al.
Transposable elements are viruslike pieces of DNA that copy and insert themselves into a host's DNA.
There are also more theoretical papers on areas such as metabolism and epigenetics, comparative analysis of gene regulatory networks, synthesis of developmental biology with evolutionary theory, and developmental control of transposable elements and the evolution of higher species.
The physical map of the Psm chromosome was elaborated using mutants obtained by transposable elements similar to and derived from pTndcat (10): pTn5catl and pTn5Spcat (Fig.
These ncRNAs play an important role in germline development, transposon silencing, epigenetic regulation, protecting the genome from invasive transposable elements, and the pathophysiology of diseases such as cancer.
All the waxy and low-amylose types arose by the insertions of transposable elements into the waxy gene.
Most remarkably, we found the genetic changes that likely underlie the evolution of pregnancy are linked to domesticated transposable elements that invaded the genome in early mammals.
