MORPHOLOGICAL STUDIES OF TRANSCRIPTION
Abstract
Preparative techniques are detailed for isolating nuclear contents of amphibian oocytes and HeLa cells for electron microscopy, and the ultrastructure of presumptive ribosomal RNA (rRNA) genes and other active chromosomal loci is described. The rRNA genes from the two cell types present strikingly similar structural configurations, both being fully loaded with RNA polymerases and exhibiting gradients of short to long nascent ribonucleoprotein (RNP) fibrils. Other chromosomal loci in the two cell types are strikingly different; those on lampbrush chromosomes of amphibian oocytes show closely-spaced polymerases and extremely long RNP fibrils, whereas those on HeLa genomes have widely-spaced polymerases and relatively short attached RNP fibrils.

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.
