Mobile DNA topics include: mobile DNA elements and multitude of transposable elements.
Mobile DNA, also known as transposable DNA elements, are DNA fragments that can be moved or copied to other regions of a genome. They are present in nearly all organisms and make up to two-thirds of the human genome.
The process of movement is often called transposion, and the mobile DNA, transposons. Some mobile DNAs move by different mechanisms to transposons, but have similarities. Mobile DNA movements are the primary engines of protein evolution, rather than replication errors. Laboratory experiments and genome sequences have documented roles for well-characterized mobile elements in the origin of novel exons and in exon shuffling.
