Figure 1 From: Multiple, non-allelic, intein-coding sequences in eukaryotic RNA polymerase genes Intein insertions into eukaryotic and viral RNA polymerases. Alignments of intein/extein borders for the eight inteins in the six RNA polymerase intein insertion sites. RNA polymerase sequences are taken from accession data as described in Methods. The unclassified Sargasso Sea sequence is from GenBank accession AACY01369547, the E. huxleyi virus 163 sequence is from GenBank accession (DQ127798). The dashes represent missing data.Back to article page
