Integration of an aberrant retrotransposon in Saccharomyces cerevisiae.

RESUMO

We describe an atypical composite Ty1 element that apparently resulted from the concurrent integration of two complete elements. A portion of the central region of one of these elements was inverted between two long terminal repeats. Inversions of this type have been detected among unintegrated retroviral circles. It now appears that such intermediates can be incorporated into the genome.
