Abstract

We have determined the complete nucleotide sequence of Xenopus laevis 28S rDNA (4110 bp). In order to locate evolutionarily conserved regions within rDNA, we compared the Xenopus 28S sequence to homologous rDNA sequences from yeast, Physarum, and E. coli. Numerous regions of sequence homology are dispersed throughout the entire length of rDNA from all four organisms. These conserved regions have a higher A + T base composition than the remainder of the rDNA. The Xenopus 28S rDNA has nine major areas of sequence inserted when compared to E. coli 23S rDNA. The total base composition of these inserts in Xenopus is 83% G + C, and is generally responsible for the high (66%) G + C content of Xenopus 28S rDNA as a whole. Although the length of the inserted sequences varies, the inserts are found in the same relative positions in yeast 26S, Physarum 26S, and Xenopus 28S rDNAs. In one insert there are 25 bases completely conserved between the various eukaryotes, suggesting that this area is important for eukaryotic ribosomes. The other inserts differ in sequence between species and may or may not play a functional role.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
