Transposable elements and circular DNAs

Circular DNAs are extra-chromosomal fragments that become circularized by genomic recombination events. We have recently shown that yeast LTR elements generate circular DNAs through recombination events between their flanking long terminal repeats (LTRs). Similarly, circular DNAs can be generated by recombination between LTRs residing at different genomic loci, in which case the circular DNA wi...

Transposable 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...

Transposable 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...

Evolutionary tinkering with transposable elements.

I t was almost 30 years ago when François Jacob declared that evolutionary innovation (the emergence of novel form and function over time) occurred primarily via a process of ‘‘tinkering’’ (1). By tinkering, Jacob essentially meant the creation of novelty through random combinations of preexisting forms. Two fundamental and countervailing notions are implicit in this view of evolution: optimali...

Functional elements residing within satellite DNAs.

Satellite DNAs represent a fast-evolving portion of the eukaryotic genome whose evolution is proposed to be driven by the stochastic process of molecular drive. Recent results indicate that satellite DNAs are subject to certain structural constraints, which are probably related to their interaction with proteins involved in the establishment of specific chromatin structures. The evolutionary pe...
