Abstract
The Tc1 element of the free-living nematode Caenorhabditis elegans is a well characterized transposon that is present in 30–500 copies per haploid genome, depending on the strain. Excision of Tc1 elements, which occurs readily in somatic tissues during larval development, has not previously been examined during aging of adult worms. We have identified a recently inserted Tc1 element in the KR1787 mutator strains of C. elegans and have found that Tc1 somatic excision at that site increases by more than 14-fold during the organism's lifespan.
