Evolution of Drosophila repetitive-dispersed DNA

We have examined the phylogenetic distribution of a spectrum of Drosophila repetitive-dispersed DNAs ranging from structurally complex transposable elements to scrambled middle repetitive sequences. Our data suggest that unlike typical "genes" these DNAs are unstable components of the dros...

Description
Summary:We have examined the phylogenetic distribution of a spectrum of Drosophila repetitive-dispersed DNAs ranging from structurally complex transposable elements to scrambled middle repetitive sequences. Our data suggest that unlike typical "genes" these DNAs are unstable components of the drosophilid genome. The unusual behavior of these repetitive-dispersed DNAs raises the possibility that this type of sequence may have an important role in the evolution of the family Drosophilidae.
