The Tc2 transposon in Caenorhabditis elegans.
A second family of transposons, named Tc2 elements, has been identified in the nematode Caenorhabditis elegans. Tc2 elements are polymorphic in sequence and are present in different numbers in different strains. Like the transposon Tc1, Tc2 is active in the germ line of some C. elegans strains. A high rate of transposition has been observed in the progeny of certain interstrain crosses, where transposition events are frequent enough to be detected in blot hybridization experiments, without the use of a genetic screen. Our data suggest that transposition of Tc1 and Tc2 may be regulated by the same genomic factors.
