Characterization and in situ hybridization mapping of Helinoto, a DNA transposon isolated in the genome of the antarctic icefish Chionodraco hamatus
The recently discovered family of helitrons, a class of RC (rolling-circle) DNA transposons particularly widespread in eukaryote kingdom, seems to be virtually very active in reshuffling the transcriptome of organisms. These elements are believed to have an important role in the host genome evolutio...
