Table 3 Variability in length and GC-content. Comparison of selected functional elements and domains within the rDNA repeat unit between the analyzed species. GC – content of GC pairs in an analyzed nucleotide sequence. In the case of species where more than one putative TIS was found, the variant with the shortest 5′ETS was considered.
