Progression of the cell cycle through mitosis leads to abortion of nascent transcripts

Abstract

Nascent transcripts of the Drosophila Ubx gene were detected by in situ hybridization. Following onset of expression, the progress of RNA polymerase (1.4 kb/min) across the gene was visualized as the successive appearance of hybridization signals from different positions within the transcription unit. Nascent transcripts disappeared at mitosis. Hybridization signals reappeared in the next cell cycle first with a 5' probe, and later, following a delay consistent with the transcription rate, with a 3' probe. Nascent transcripts were observed continuously in expressing cells of a mutant embryo in which cells are blocked in interphase. We conclude that progression through mitosis causes abortion of nascent transcripts and suggest that periodic abortion of transcription contributes to regulation of expression of large genes.

  • Pioneering biochemical studies estimated average RNA Pol II speed between 1.1 kb/min and 4.8 kb/min on a few genes.

    “By monitoring the appearance of RNA by in situ hybridization, nuclear run‐on, slot blot, or RT–PCR after expression activation, RNA Pol II speed was estimated between 1.1 kb/min and 4.8 kb/min (Ucker & Yamamoto, 1984; Thummel et al, 1990; Shermoen & O'Farrell, 1991; O'Brien & Lis, 1993; Tennyson et al, 1995; Femino et al, 1998; Femino et al, 2003; Hanisch et al, 2013).”

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.
