B delloid rotifers, microscopic animals found nearly all in freshwater ecosystems worldwide, lack the enzymes that most animals use to silence regions of their genome by attaching chemical tags called ...
Transposable elements enable a sub-population of the bacterium Burkholderia thailandensis to duplicate a large region of DNA, which helps them to form biofilms in challenging environments. Open ...
Insertion sequences (ISs) are the simplest transposable elements and are widely distributed in bacteria. It has long been thought that IS excision rarely occurs in bacterial cells because most ...
Wagner, A. (2006) Periodic extinctions of transposable elements in bacterial lineages Evidence from intragenomic variation in multiple genomes. Molecular Biology and Evolution, 23, 723-733. doi10.1093 ...
For example, Tn, bacterial composite elements (elements flanked by Insertion Sequences), provide several examples in which a gene involved in antibiotic resistance can be horizontally transferred ...
Composite transposable elements are moving as one unit within a genome and are copying and inserting genes enclosed by itself. The following traits of composite transposable elements are making their ...
Human disease agents can get transmitted both horizontally-through infection-and vertically-from parent to offspring. Depending on details of their evolutionary dynamics, they may increase or decrease ...
Transposable elements are sequences in genomes that can change their position in the genome. Thus, they are also called “jumping genes”. They are able to affect the composition and size of genetic ...
Bacterial mutations, transformation, transduction, conjugation, recombination, plasmids, transposable elements, gene cloning and the control of genetic expression in bacteria and their viruses. This ...
