Retrotransposon transposition intermediates are encapsidated into virus-like particles.
Virus-like particles (VLPs) possessing reverse transcriptase activity are persistently present in Drosophila melanogaster cultured cells and are formed in yeast induced for transposition. Different retrotransposon transposition intermediates consistent with those expected from the model of reverse transcription pathway of retrotransposon transposition have been detected during the analysis of nucleic acids isolated from VLPs. These data indicate that the act of reverse transcription takes place in VLPs which may be considered as functional intermediates of transposition.
