  • RECOMBINATION between a diffusible reverse transcript and its homologous chromosomal allele has been proposed as a mechanism for the precise removal of introns from DNA and gene conversion of dispersed repeated sequences1,2. We have reported that RNA-mediated recombination occurs in the yeast Saccharomyces cerevisiae3. This recombination requires expression of the retrotransposon Ty, and results in intron loss from a plasmid-borne marker gene and the formation of pseudogenes. Because the… CONTINUE READING
