The Osvaldo retrotransposon has shown a high transposition rate in some strains of Drosophila buzzatii and in hybrids between D. buzzatii and its sibling D. koepferae. In order to understand the molecular basis of this phenomenon, we developed a procedure to clone a recently transposed copy with the aim of characterizing an active, full- length Osvaldo element. The complete nucleotide sequence of Osvaldo, obtained from a recent insertion site, was determined. Osvaldo is 9,045 bp long and is… CONTINUE READING
