Abstract

Ribosomal RNA sequence variants are conserved, exhibit tissue-specific expression, and are found in actively translating ribosomes.

  • Only a part of rDNA units is transcriptionally active at any time, while the rest, or even the majority of rDNA repeats, are in a repressed state.

    “Numerous genetic, microscopic and biochemical studies have demonstrated that only a part of rDNA units is transcriptionally active at any time, while the rest, or even the majority of rDNA repeats, are in a repressed state (6–14).”

    From Impaired function of rDNA transcription initiation machinery leads to derepression of ribosomal genes with insertions of R2 retrotransposon (2022) · cites this paper as [12]

    The Introduction (page unavailable) describes silencing of distinct rDNA subtypes, and the Results section on expression between organs (page unavailable) notes methylation of nonexpressed rDNA regions. These passages support the existence of active and repressed units, but do not establish that most repeats are repressed or quantify the active fraction at any given time. (LLM, conf=0.84)

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.
