Salt-induced and supercoiling-induced B-Z junctions in pWR756, a plasmid containing (GC)16, were probed with bisulfite-methoxyamine, a modification reagent specific for single-stranded nucleic acids. The modification sites were analyzed with S1 nuclease and the modified cytosines were determined from termination sites of DNA chain elongation by DNA polymerase. The results showed that most accessible cytosines are the same for both types of B-Z junctions.

UI MeSH Term Description Entries
D004277 DNA, Single-Stranded A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle. Single-Stranded DNA,DNA, Single Stranded,Single Stranded DNA
D004278 DNA, Superhelical Circular duplex DNA isolated from viruses, bacteria and mitochondria in supercoiled or supertwisted form. This superhelical DNA is endowed with free energy. During transcription, the magnitude of RNA initiation is proportional to the DNA superhelicity. DNA, Supercoiled,DNA, Supertwisted,Supercoiled DNA,Superhelical DNA,Supertwisted DNA
D004587 Electrophoresis, Agar Gel Electrophoresis in which agar or agarose gel is used as the diffusion medium. Electrophoresis, Agarose Gel,Agar Gel Electrophoresis,Agarose Gel Electrophoresis,Gel Electrophoresis, Agar,Gel Electrophoresis, Agarose
D006898 Hydroxylamines Organic compounds that contain the (-NH2OH) radical.
D012492 Salts Substances produced from the reaction between acids and bases; compounds consisting of a metal (positive) and nonmetal (negative) radical. (Grant & Hackh's Chemical Dictionary, 5th ed) Salt
D013447 Sulfites Inorganic salts of sulfurous acid. Sulfite,Sulfites, Inorganic,Inorganic Sulfites
D015394 Molecular Structure The location of the atoms, groups or ions relative to one another in a molecule, as well as the number, type and location of covalent bonds. Structure, Molecular,Molecular Structures,Structures, Molecular
D015719 Single-Strand Specific DNA and RNA Endonucleases Enzymes that catalyze the endonucleolytic cleavage of single-stranded regions of DNA or RNA molecules while leaving the double-stranded regions intact. They are particularly useful in the laboratory for producing "blunt-ended" DNA molecules from DNA with single-stranded ends and for sensitive GENETIC TECHNIQUES such as NUCLEASE PROTECTION ASSAYS that involve the detection of single-stranded DNA and RNA. Single Strand Specific DNA and RNA Endonucleases
