In other words, the absence of massive transposition is probably because a moderate strength of the reaction norm had previously been selected for.
Southern hybridizations demonstrated the absence of major transposition events and genome rearrangements for A. asiaticus during a time period of 984 days.
Database mining of the C. owczarzaki genome and transcriptome was therefore employed to produce four lines of evidence, in the absence of observed transposition, to investigate element activity within the C. owczarzaki population.
For comparison we also examined whether IS persistence is still favoured by more IS-induced adaptive mutations in the absence of bursts in transposition rates (Fig. 6, bottom panels, thick grey).
Anomalies are those of absence, transposition, torsion (twisting), and duplication of the penis.
In the absence of TnsD and TnsE, transposition mediated by a hyperactive TnsABC* occurs into many different target sites with low selectivity [26].
Eukaryotic TEs can be divided into two major classes, retrotransposons (class I) and DNA transposons (class II), on the basis of the presence or absence of RNA as a transposition intermediate [4].
Transposition, absence of limitation to extension and preservation of a long flexible lumbar region are a unique human configuration that relates to the uniquely habitual upright bipedalism seen in our species and lineage.
TEs represent one of several types of repetitive sequences and they can be classified into either of two classes according to the presence or absence of RNA as a transposition intermediate, retrotransposons or DNA transposons, respectively (8).
Second, there is a near absence of nuclear gene retro-transposition in birds relative to mammals (Haas et al. 2001; Warren et al. 2010) but see (Ellegren 2011).
On the other hand, prior studies with IS 6100-based transposons suggested independent transposition and absence of a target site preference.
