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...
متن کاملRepetitive elements in the major histocompatibility complex (MHC) class I region of a teleost, medaka: identification of novel transposable elements
The repetitive elements of medaka (Oryzias latipes) are poorly characterized in spite of recent rapid progress in the medaka genome analysis. Here we report the characterization of the repetitive elements in the major histocompatibility complex (MHC) class I region, which spans about 400 kb and is one of the best characterized regions of the medaka genome. Microsatellite, low complexity regions...
متن کاملTransposable 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...
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 کاملEvolutionary 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...
