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 of maize transposable elements is correlated with activity
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1990Abstract Transposition of the maize transposable elements Ac, Spm and Mu is correlated with a lack of methylation. For both Ac (Schwartz & Dennis 1986) and Spm (Fedoroff et al. 1988) methylation of a region upstream and downstream of the site of initiation of transcription results in a loss both of mRNA encoding for the ...

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 ...

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).

| 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

Analysis of the cis-acting DNA elements required for piggyBac transposable element excision
Molecular and General Genetics MGG, 1997The terminal DNA sequence requirements for piggyBac transposable element excision were explored using a plasmid-based assay in transfected, cultured insect cells. A donor plasmid containing duplicate 3' piggyBac terminal inverted repeats was constructed that allowed individual nucleotides or groups of nucleotides within one of the 3' repeats to be ...

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.

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.
