composite transposon
英[ˈkɔmpəzit trænsˈpəusɔn]美[kəmˈpɑzɪt trænsˈpozɑn]
A composite transposon is similar in function to simple transposons and Insertion Sequence (IS) elements in that it has protein coding DNA segments flanked by inverted, repeated sequences that can be recognized by transposase enzymes. A composite transposon, however, is flanked by two separate IS elements which may or may not be exact replicas.
