Abstract

The eukaryotic transposable element Ty1 is present in about 20–30 integrated copies per yeast aploid genome, variably localized in different strains. Here, we report the presence in yeast of circular extrachromosomal molecules homologous to Ty1, 6 kilobases in size (the same as integrated copies) present in about 1 circular copy/250–300 cells. This finding shows another analogy between eurkaryotic-transposable elements and the pro-viral integrative form of retroviruses.
