P Element In The Drosophila Melanogaster

PDF

Transposable elements propagate in eukaryotes as successfully as in prokaryotes. The genetic background of eukaryotes includes a variety of elements that possess the ability to move to randomly selected new locations within the genome in which they reside. Eukaryotic transposable elements can be divided into two general groups : One group of elements is comparable to bacterial transposons. The elements end in short inverted repeats and generate short direct repeats of target DNA at the site of insertion. Like bacterial transposons, these elements have no life outside the genome. Whether valuable components playing a role in cellular survival or selfish parasites concerned only with their own survival, they have no independent existence and do not generate free molecules of DNA. The best characterized are the controlling elements of maize and the P elements of D.melanogaster discussed.
