Sentence examples for responsible for transposition from inspiring English sources
The other TEs contained multiple stop codons within the sequences encoding the proteins responsible for transposition.
The integrase intTn gene is responsible for transposition, and the excisase xis gene may increase the frequency of excision but is not required [ 37].
The region between those repeats includes two overlapping reading frames, orfA and orfB, encoding for a transposase, an enzyme responsible for transposition of the insertion sequence.
However, this largest element is non-coding and presents no homology with any known proteins, so the autonomous partner responsible for transposition is still unidentified.
Autonomous non-LTR retrotransposons (long interspersed nuclear elements, LINEs) are thought to be responsible for transposition of non-autonomous short interspersed nuclear elements (SINEs) (4).
Particularly interesting among Acinetobacter plasmids is the pKLH2 family [ 35], a group of evolutionary related plasmids harboring mercury resistance genes (mer) embedded in a single compact operon that, in turn, has been suggested to represent an aberrant mercury resistance transposon (namely TndPKHLK2) that has lost genes responsible for transposition [ 36].
In fact, mercury resistance genes (mer) have been usually found embedded in a single compact operon [ 42] that, in turn, has been suggested to represent an aberrant mercury resistance transposon (namely TndPKHLK2) that, in some cases, has lost those genes responsible for its transposition [ 43].
When considering the evolutionary dynamics of S. pombe LTR elements, Kelly and Levin [ 21] speculated if only a few of the complete elements were responsible for majority of transposition events (by necessity preceded by transcriptional activity) as has been observed in Saccharomyces cerevisiae [ 31].
Although inversions are thought to be the predominant mode of gene rearrangement in chloroplast genomes (Palmer 1991; Boudreau and Turmel 1995, 1996), we cannot exclude the possibility that other evolutionary mechanisms, such as transpositions or duplicative transpositions are responsible for some of the observed changes in gene order between the Stigeoclonium and Schizomeris cpDNAs.
Such sudden releases of transposon activity may be jointly responsible for genome rearrangements and the transposition of the sdY, with both contributing to rapid speciation.
The Drosophila ovary is composed of both somatic and germ cells, and in both cell types a highly conserved class of small noncoding RNAs, piRNAs (Piwi-interacting RNAs), are responsible for silencing TE expression and transposition (Guzzardo et al. 2013).
