Indeed, the large grape genomic gaps are frequently bordered by 5 bp direct repeats, reminiscent of a type of DNA excision mediated by a precise process of transposition [89].
b) A second example is the precise nature of Dionysius' transposition of Neoplatonic structure.
PGBD5-induced DNA transposition is precise with preference for insertions at TTAA genomic sites.
The sequence surrounding an inserted ERIC remains unchanged, indicating a precise insertion or deletion event via a mechanism distinct from classic transposition mechanisms [ 23, 24].
Precise examples of PAVs, CNVs, inversion, duplication, and movement (i.e., transposition) characterized in grasses are given.
Molecular analysis of these loci demonstrated a precise integration of these elements into recipient chromosomes with genetic footprints diagnostic of transposition.
DNA transposition catalyzed by PGBD5 in human cells occurs genome-wide, with precise transposon excision and preference for insertion at TTAA sites.
The precise mechanism for this translocation is unknown, but is likely to be either by transposition of a tandem duplicate of an ancestral β-globin gene, or retrotransposition of an intron-containing primary transcript.
The precise roles of these factors in the development of chromosomal instability and retro-transposition require further study.
DNA transposition by piggyBac superfamily transposases is distinguished from most other DNA transposon superfamilies by the precise excision of the transposon from the donor site and preference for insertion in TTAA sites (Cary et al., 1989; Fraser et al., 1995).
Considering all the data available so far, it is not possible to determine the precise mechanism responsible for rearrangements in this transition (tandem duplication-random loss [ 73], inversion [ 71], transposition [ 74], and/or intramolecular recombination [ 72]).
