abstract：:U6 RNA is a member of a class of small abundant stable nuclear RNAs that are essential for splicing. In all species examined so far, the U6 RNA is a RNA polymerase III transcript. The U6 gene of the fission yeast Schizosaccharomyces pombe is unusual in that it is interrupted by an intron whose structure is similar to ...
