Quasispecies in retrotransposons: a role for sequence variability in Tnt1 evolutioneferred to as ‘quasispecies’. This huge swarm of different sequences constitutes a reservoir of potentially useful genomes in case of an environmental change, endowing retroviruses with extreme adaptability. Retrotransposons are mobile genetic elements closely related to retroviruses, and retrotrans

Genetic and molecular investigations on the endogenous mobile elements of non-drosophilid fruitfliesl traits observed appears to be the phenotypic expression of a complex interacting dysgenic system of inducer and suppressor effects; probably more than one system is activated in the crosses. This suggests that different systems of mobile elements occur in different strains and populations of C. ..

Plant S1 SINEs as a model to study retroposition species of the . tribe. We propose that S1 amplification in . could represent a good eukaryotic model to study retroposition. This is based on the fact that S1 elements share clear structural and evolutionary characteristics with mammalian SINEs but are present in a much lower copy number (500 loci

Accumulation of transposable elements in laboratory lines of ,mic equilibrium between transposition to new sites and natural selection eliminating copies. the force of natural selection opposing TE multiplication is partly relaxed in inbred laboratory lines of flies. the average rate of TE transposition is from 2.6 × 10. to 5.0 × 10. per copy per generation, a
