Abstract

A multipurpose plasmid, pUR222, was constructed. It contains six unique cloning sites (PstI, SalI, AccI, HindII, BamHI and EcoRI) in a small region of its lac Z-gene part. Insertion of foreign DNA into the plasmid can be easily detected. Bacteria harbouring recombinant plasmids generally give rise to white colonies, while those containing only vector DNA form blue colonies on indicator plates. Plasmid DNA purified by a rapid method (Birnboim, H.C. and Doly, J. (1979) Nucl. Acids. Res. 7, 1513-1523) can be used for chemical sequencing of the cloned insert DNA. Labeled fragments need not be isolated after cutting with the proper restriction enzymes and are treated directly according to the sequencing protocol of Maxam and Gilbert.

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.
