متن کاملThe population biology of transposable elements
A transposable element can be defined as a DNA sequence capable of moving to new sites in the genome. Such DNA sequences have been described in a wide range of organisms. The evolutionary processes affecting transposable elements can thus be divided into two categories: changes in sequence and changes in genomic location. As with other types of evolutionary change, the nature of the evolutionar...
متن کاملThe population biology of transposable elements.
There is much debate about the significance of transposable elements for the organisms that host them, and the nature of the forces responsible for maintaining them in the host population. Recent theoretical and experimental studies of the population biology of transposons have shed light on these controversies.
متن کاملCompetition between transposable elements and mutator genes in bacteria.
Although both genotypes with elevated mutation rate (mutators) and mobilization of insertion sequence (IS) elements have substantial impact on genome diversification, their potential interactions are unknown. Moreover, the evolutionary forces driving gradual accumulation of these elements are unclear: Do these elements spread in an initially transposon-free bacterial genome as they enable rapid...
متن کاملDomestication of Transposable Elements into MicroRNA Genes in Plants
Transposable elements (TE) usually take up a substantial portion of eukaryotic genome. Activities of TEs can cause genome instability or gene mutations that are harmful or even disastrous to the host. TEs also contribute to gene and genome evolution at many aspects. Part of miRNA genes in mammals have been found to derive from transposons while convincing evidences are absent for plants. We fou...
