Figure 1From: LTR retrotransposons and the evolution of dosage compensation in DrosophilaStructure of the copia LTR-CAT construct. Position of Apa I site (274 bp) and the 5' (14 bp) and 3' (485 bp) PCR primer binding sites are shown (LTR = 5' copia long terminal repeat; ULR= copia untranslated leader region; CAT= bacterial chloramphenicol acetyltransferase reporter gene (see Methods for primer sequences).Back to article page
