A genetic map of quantitative trait loci for body weight in the mouse.

abstract：:TE146 is a giant transposon of Drosophila melanogaster. It carries two copies of the white and roughest genes, normally found on the X chromosome. The structure of this transposon has been studied at the molecular level. TE146 may transpose to new chromosome positions, excise and be lost from the genome or undergo int...

abstract：:Phylogenetic analyses of non-LTR retrotransposons suggest that all elements can be divided into 11 lineages. The 3 oldest lineages show target site specificity for unique locations in the genome and encode an endonuclease with an active site similar to certain restriction enzymes. The more "modern" non-LTR lineages po...
