1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

During transcription elongation the nascent RNA remains base-paired to the template strand of the DNA before it is displaced and the two strands of the DNA reanneal, resulting in the formation of a transcription "bubble" of approximately 10 bp. To examine how the length of the RNA-DNA hybrid is maintained, we assembled transcription elongation complexes on synthetic nucleic acid scaffolds that mimic the situation in which transcript displacement is compromised and the polymerase synthesizes an extended hybrid. We found that in such complexes bacterial RNA polymerase exhibit an intrinsic endonucleolytic cleavage activity that restores the hybrid to its normal length. Mutations in the region of the RNA polymerase near the site of RNA-DNA separation result in altered RNA displacement and translocation functions and as a consequence in different patterns of proofreading activities. Our data corroborate structural findings concerning the elements involved in the maintenance of the length of the RNA-DNA hybrid and suggest interplay between polymerase translocation, DNA strand separation, and intrinsic endonucleolytic activity.
