DNA sequence of the maize transposable element Dissociation
Nature, 1984The DNA sequence of the terminal 4.2 kilobases (kb) of the 30-kb insertion in the endosperm sucrose synthase gene of maize mutant sh-m5933 shows that it comprises two identical 2,040-base pair (bp) segments, one inserted in the reverse direction into the other. We suggest that the 2,040-bp sequence is an example of the transposable element Dissociation

IS1294, a DNA Element That Transposes by RC Transposition
Plasmid, 2000IS1294, found on the ColD-like resistance plasmid pUB2380, is IS91-like. It is an active 1.7-kb insertion sequence that lacks terminal inverted repeats, displays insertion-site specificity, and does not generate direct repeats of the target site. The element has one large open reading frame, tnp(1294), encoding a transposase of 351 amino acids, related

Transposable elements and DNA transposition in eukaryotes
Current Opinion in Cell Biology, 1990An interesting and surprising outcome of the last 15 years of Investigation into the organization of DNA sequences in eukaryotic genomes is the realization that a substantial proportion of each genome is made up of transposable DNA sequences. These sequences occur in families of repeated elements that may make up l&15% of the genome.

DNA sequence of the transposable element IS1
Molecular and General Genetics MGG, 1979The nucleotide sequence of an IS1 element recently transposed into the lacI gene is reported. This sequence is nearly identical to one previously reported for another IS1 element (Ohtsubo and Ohtsubo, 1978). The implications of this similarity are discussed.

DNA methylation dynamics at transposable elements in mammals
Essays in Biochemistry, 2019Abstract Transposable elements dominate the mammalian genome, but their contribution to genetic and epigenetic regulation has been largely overlooked. This was in part due to technical limitations, which made the study of repetitive sequences at single copy resolution difficult. The advancement of next-generation sequencing assays in the

Potential movement of transposable elements through DNA circularization
Current Genetics, 2016The generation of circular DNAs is a relatively unrecognized type of genomic structural variation, but recent findings point to a possible role of circular DNAs in the movement of transposable elements. Circularization of genomic DNA is observed across eukaryotic species, in a range of different cell types, and from all parts of the genome.

| Transposable elements as selfish DNA
1995Abstract Biologists seek functional explanations for the attributes of organisms. Such explanations show the advantage that the attribute gives to the organism. Any attribute, including components of the genome, can potentially be explained in this way. The belief that such functional explanations are appropriate rests on the tenet of

Population genetics of transposable DNA elements
Genetica, 1992This paper is an attempt to bring together the various, dispersed data published in the literature on insertion polymorphism of transposable elements from various kinds of populations (natural populations, laboratory strains, isofemale and inbred lines).

Structural and functional liaisons between transposable elements and satellite DNAs
Chromosome Research, 2015Transposable elements (TEs) and satellite DNAs (satDNAs) are typically identified as major repetitive DNA components in eukaryotic genomes. TEs are DNA segments able to move throughout a genome while satDNAs are tandemly repeated sequences organized in long arrays.

DNA sequence of a foldback transposable element in Drosophila
Nature, 1982The bizarre structures of the Drosophila foldback (FB) transposable elements are discussed here, and arguments favouring a transposase-mediated mobility are presented. The complete 4,089-base pair nucleotide sequence of transposable element FB4 reveals the full pattern of periodicity within the inverted repeats and the nature of the loop-inverted ...
