The first steps of transposable elements invasion: parasitic strategy vs. genetic drift.
Transposable elements are often considered as selfish DNA sequences able to invade the genome of their host species. Their evolutive dynamics are complex, due to the interaction between their intrinsic amplification capacity, selection at the host level, transposition regulation, and genetic drift. Here, we propose modeling the first steps of TE invasion, i.e., just after a horizontal transfer,...
متن کاملTransposable genetic elements.
N atural selection, as Darwin rec ognized more than a centu ry ago, favors individuals and populations that acquire traits con ducive to survival and reproduction. The generation of biological variation, which gives rise to new and potentially advantageous combinations of genetic traits, is therefore a central requirement for the successful evolution of species in diverse and changing enviro...
متن کاملTransposable elements in Drosophila
Transposable elements (TEs) are mobile genetic elements that can mobilize within host genomes. As TEs comprise more than 40% of the human genome and are linked to numerous diseases, understanding their mechanisms of mobilization and regulation is important. Drosophila melanogaster is an ideal model organism for the study of eukaryotic TEs as its genome contains a diverse array of active TEs. TE...
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.
