Transposable elements in mosquitoes
Cytogenetic and Genome Research, 2005We describe the current state of knowledge about transposable elements (TEs) in different mosquito species. DNA-based elements (class II elements), non-LTR retrotransposons (class I elements), and MITEs (Miniature Inverted Repeat Transposable Elements) are found in the three genera, <i>Anopheles, Aedes</i> and <i>Culex</i> ...

Transposable elements (TEs) are low-complexity elements (e.g., LINEs, SINEs, SVAs, and HERVs) that make up to two-thirds of the human genome. There is mounting evidence that TEs play an essential role in molecular functions that influence genomic plasticity and gene expression regulation.

Mosquito transposable elements
Insect Biochemistry and Molecular Biology, 2004The completion of the genome assembly for the African malaria mosquito, Anopheles gambiae, and continuing genomic efforts for the yellow fever mosquito, Aedes aegypti, have allowed the use of bioinformatics tools to identify and characterize a diverse array of transposable elements (TEs) in these and other mosquito genomes. An overview of the types and

Current Biology, 1992
Transposable elements comprise a major fraction of eukaryotic genomes. They are studied both because of their intrinsic biological interest and because they can be exploited as valuable research tools. Many interesting papers dealing with various aspects of the biology of these elements have been published during the past year and a number of new ...

Annual Review of Genetics, 1989
Of the ten transposable element systems that have been genetically identified in maize (listed in 55), two have contributed most of the molecular data. These are the Enhancer (En) or Suppressor-mutator (Spm) system and the Activator (Ac) system. With a certain preference for En/Spm, these two systems are used as the principle examples to outline the ...

Mosquito transposable elements
Genetica, 1994Most of the transposons so far characterized from mosquito genomes are retroelements which seem to be distributed worldwide. The Juan transposons constitute a family of non-LTR retroelements, or LINE-retroposons, which are dispersed in the genomes of several mosquito species.

Transposable Elements and Fitness of Bacteria [PDF]
Theoretical Population Biology, 2002 A stochastic model was designed to describe the evolution of bacterial cultures during 10,000 generations. It is based on a decreasing law for the generation of beneficial mutations as they become fixed in the genomes. Seven beneficial mutations on average were necessary to improve the relative fitness from 1.0 to 1.43 and the model was consistent with

Evolution of transposable elements
Journal of Antimicrobial Chemotherapy, 1986Transposable elements are at an advantage compared with other DNA sequences. This has led to the generation of transposable systems from a variety of different sources. Once fabricated, these elements can very simply acquire accessory genes, such as those that encode resistance to antibiotics.

Transposable Elements and Cancer
1986Tumor progression is accompanied by many chromosomal aberrations and DNA rearrangements which contribute to the aggressiveness of the tumor. It is possible that active transposition of DNA elements play a role in these events. Approximately one third of the mammalian genome is composed of repetitive sequences (103 — 105 copies).

Transposable Elements in Nematodes
1994Transposable elements are present in the genomes of most, if not all, organisms. Because of their ability to insert into and excise from the chromosomes of their hosts transposons are a significant source of spontaneous mutations in organisms. Therefore they can be used as a tool for cloning genes that have been identified by mutations and for which no
