pBR322 restriction map derived from the DNA sequence: accurate DNA size markers up to 4361 nucleotide pairs long

Open access
Sutcliffe, J.Gregor·1978·Nucleic Acids Research

Abstract

I have derived a complete restriction map of pBR322 from the total nucleotide sequence of the plasmid. Most of the restriction sites also have been demonstrated empirically. The exact sizes of all restriction fragments and the relative positions of the cuts are presented. These fragments can serve as accurate DNA size markers from small pieces up to the 4362 base pair length of pBR322. Inserts cloned in this vector may be characterized easily using this data.

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.
