Generating and manipulating transgenic animals using transposable elements
Transposable elements, or transposons, have played a significant role in the history of biological research. They have had a major influence on the structure of genomes during evolution, they can cause mutations, and their study led to the concept of so-called "selfish DNA". In addition, transposons have been manipulated as useful gene transfer vectors. While primarily restricted to use in inve...
متن کاملPerspective : Transposable Elements , Parasitic Dna , and Genome
The nature of the role played by mobile elements in host genome evolution is reassessed considering numerous recent developments in many areas of biology. It is argued that easy popular appellations such as ‘‘selfish DNA’’ and ‘‘junk DNA’’ may be either inaccurate or misleading and that a more enlightened view of the transposable element-host relationship encompasses a continuum from extreme pa...
متن کاملTransposable elements and host genome evolution.
Several recent reports have challenged the idea that transposable elements (TEs) are mainly 'selfish' or 'junk' DNA with little importance for host evolution. It has been proposed that TEs have the potential to provide host genomes with the ability to enhance their own evolution. They might also be a major source of genetic diversity, allowing response to environmental changes. Because the rela...
متن کاملExpression of Transposable Elements in Neural Tissues during Xenopus Development
Transposable elements comprise a large proportion of animal genomes. Transposons can have detrimental effects on genome stability but also offer positive roles for genome evolution and gene expression regulation. Proper balance of the positive and deleterious effects of transposons is crucial for cell homeostasis and requires a mechanism that tightly regulates their expression. Herein we descri...
متن کاملEvolutionary active transposable elements in the genome of the coelacanth.
The apparent morphological stasis in the lineage of the coelacanth, which has been called a "living fossil" by many, has been suggested to be causally related to a slow evolution of its genome, with strongly reduced activity of transposable elements (TEs). Analysis of the African coelacanth showed that at least 25% of its genome is constituted of transposable elements including retrotransposons...
