Complex patterns of transcription of a Drosophila retrotransposon in vivo and in vitro by RNA polymerases II and III.


The mdg1 retrovirus-like retrotransposon of Drosophila melanogaster was found to possess a complex promoter which can be transcribed by both RNA polymerases II and III (pol II and pol III). Pol III transcription, which is not typical of protein-coding genes, is driven by the sequences located in the long terminal repeat (LTR) of mdg1, predominantly within… (More)
