Mobilome
Encyclopedia
The mobilome is the total of all mobile genetic elements
in a genome
. Elements that can move within the genome (transposable elements) are the major constituents of the mobilome in eukaryote
s. In prokaryote
s, however, mobile genetic elements that can move between genomes, like prophage
s and plasmid
s, are also an important part of the mobilome.
Mobile genetic elements
Mobile genetic elements are a type of DNA that can move around within the genome. They include:*Transposons **Retrotransposons**DNA transposons**Insertion sequences*Plasmids...

Genome
In modern molecular biology and genetics, the genome is the entirety of an organism's hereditary information. It is encoded either in DNA or, for many types of virus, in RNA. The genome includes both the genes and the non-coding sequences of the DNA/RNA....

Eukaryote
A eukaryote is an organism whose cells contain complex structures enclosed within membranes. Eukaryotes may more formally be referred to as the taxon Eukarya or Eukaryota. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear...
s. In prokaryote
Prokaryote
The prokaryotes are a group of organisms that lack a cell nucleus , or any other membrane-bound organelles. The organisms that have a cell nucleus are called eukaryotes. Most prokaryotes are unicellular, but a few such as myxobacteria have multicellular stages in their life cycles...
s, however, mobile genetic elements that can move between genomes, like prophage
Prophage
A prophage is a phage genome inserted and integrated into the circular bacterial DNA chromosome. A prophage, also known as a temperate phage, is any virus in the lysogenic cycle; it is integrated into the host chromosome or exists as an extrachromosomal plasmid. Technically, a virus may be called...

Plasmid
In microbiology and genetics, a plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA. They are double-stranded and, in many cases, circular...
