Primary Sequence of U-1 Nuclear Ribonucleic Acid of Novikoff Hepatoma Ascites Cells
Open accessAbstract
The U-1 RNA is one of the low molecular weight nuclear RNAs of Novikoff hepatoma ascites cells that is specifically localized to the extranucleolar portion of the nucleus. After the RNA was purified by polyacrylamide gel electrophoresis, it was subjected to various enzymatic digestion procedures for determination of its primary nucleotide sequence. The U-1 RNA contains 171 nucleotides. Its 5′ end is an alkali-stable tetranucleotide containing N2,2,7-trimethyl guanylic acid. The primary sequence of U-1 RNA is: (m32,2,7G, Am, Um) [see PDF for sequence]

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.
