A dye-buoyant-density method for the detection and isolation of closed circular duplex DNA: the closed circular DNA in HeLa cells.
Open accessAbstract
Covalently closed circular duplex DNA's are now known to be widespread among living organisms. This DNA structure, originally identified in polyoma viral DNA,(1,2) has been assigned to the mitochondrial DNA's in ox(3) and sheep heart,(4) in mouse and chicken liver,(3) and in unfertilized sea urchin egg.(5) The animal viral DNA's--polyoma, SV40,(6) rabbit(7) and human(8) papilloma--the intracellular forms of the bacterial viral DNA's φX174,(9,10) lambda,(11,12) M13,(13) and P22(14) -- and a bacterial plasmid DNA, the colicinogenic factor E2,(15) have all been shown to exist as closed circular duplexes. Other mitochondrial DNA's(16,17) and a portion of the DNA from boar sperm(18) have been reported to be circular, but as yet have not been shown to be covalently closed.

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.
