... transposable element Many biologists, if pressed, invoke `adaptation by natural selection' as an answer to this question. For some biologists, the answer stops there. How else could the extraordinary biochemical–physiological traits that so obviously enable organisms to function in diverse environments...

... chromosomal integration. Post-integration behavior will determine whether the transposable elements being employed currently as primary gene vectors will be useful as gene-tagging and enhancer-trapping agents. The post-integration behavior of existing insect vectors has not been extensively examined. Mos1...

... factor HSF, which is similar in T and Oregon R flies. Rather, the reduced expression may stem from insertion of two transposable elements, H.M.S. Beagle in the intergenic region of the 87A7 hsp70 gene cluster and Jockey in the hsp70Ba gene promoter. We hypothesize that the reduced Hsp70 expression...
