The successful application of transposon tagging requires previous identification and cloning of a transposon in the species under consideration.
- An alternative approach to the use of retroviruses was to use a DNA transposon to integrate DNA into zebrafish chromosomes.2003, Karl J. Clark, The Development of Sleeping Beauty Gene-trap Transposons for Insertional Mutagenesis of Vertebrates, University of Minnesota, page 7:
