Pustell DNA matrix (DotPlot) of 7,531 bp of Schistosoma mansoni genomic DNA sequenced from BAC clone 33-N-3, revealing two identical 386 bp repeat sequences flanking 5,515 bp of unique sequence. A schematic representation of the 6,287 bp retrotransposon encoded by the sequence is shown below the matrix, with the positions of the LTRs and several domains (CHB, Cys-His Box; PR, protease; RT, reverse transcriptase; RH, RNaseH; IN, integrase) labeled. The position of the probe employed in library screening and Southern hybridization is indicated by a red box above this schematic representation. Both matrix and schematic are to scale.
