Superhelix density heterogeneity of intracellular simian virus 40 deoxyribonucleic acid.
Covalently closed intracellular and viral simian virus 40 (SV40) deoxyribonucleic acid (DNA) were separately isolated from infected African green monkey cells (BSC-1) grown in culture. The two DNA species form overlapping bands centered at different positions in a propidium di-iodide-cesium chloride (PDI-CsCl) buoyant density gradient capable of separating closed DNA species with different supe...
متن کاملHeterogeneity of deoxyribonucleic acid molecules isolated from Mycobacterium smegmatis.
Bulk chromosomal deoxyribonucleic acids (DNAs) of Mycobacterium smegmatis strains 607+ (wild type) and 607-1 (Strr) and orange-red pigmented variants (OR) were separated into two distinct bands (types 1 and 2) by cesium chloride density gradient centrifugation. Thermal denaturation analyses showed that type 1 and 2 DNA fragments of these strains possessed guanine plus cytosine contents averagin...
متن کاملSequence heterogeneity in closed simian virus 40 deoxyribonucleic acid.
The heteroduplex molecules formed by self-annealing of denatured, singly nicked simian virus 40 (SV40) deoxyribonucleic acid (DNA) prepared from closed viral DNA were examined by formamide-protein film electron microscopy to test the DNA for sequence homogeneity. Sequence inhomogeneity appears in the heteroduplexes as single-strand loops. These result from sequence deletion or from sequence sub...
متن کاملCharacterization of deoxyribonucleic Acid species from castor bean endosperm: inability to detect a unique deoxyribonucleic Acid species associated with glyoxysomes.
Three DNA buoyant density species (nuclear, 1.692 g cm(-3); mitochondria 1.705 g cm(-3); and proplastid, 1.713 g cm(-3)) can be detected in extracts from castor bean endosperm. No other buoyant density species can be identified. DNA extracts from sucrose density gradient purified glyoxysomes exhibit varying amounts of each of the three identified DNAs but no other distinguishable DNA species. R...
متن کاملDeoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.
Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...
