SIRV2 is a double-stranded DNA virus that infects Sulfolobus islandicus , an archaeon that lives in an environment with temperatures around 80 o C and a pH of 3. Egelman, Prangishvili and colleagues have now investigated how SIRV2 maintains its genomic integrity under such extreme conditions....
DNA n. scientifically, deoxyribonucleic acid, a chromonal double chain (the famous "double helix") in the nucleus of each living cell the combination of which determines each individual's hereditary characteristics. In law, the importance is the discovery that each person's DNA is different and...

Emergence of the B/A junction has been directly confirmed with the use of distamycin A and netropsin, ligands known to selectively bind to AT stretches of B-DNA. It can be shown that both ligands suppress formation of the A-form in the B-philic part. The free energy value for the B/...
Carnation small viroid-like RNA (CarSV RNA) is a small (275nt), circular molecule which is unique among plant viroid-like RNAs in having a tandemly repeated homologous DNA. This DNA form was found fused to DNA sequences of carnation etched ring caulimovirus (CERV) in certain Spanish carnat...
By Megan Fellman,Northwestern University (Medical Xpress) -- Northwestern University chemists have synthesized a new form of DNA, one that can begin to be used to create new gene regulation therapies, for the prevention or treatment of diseases such as cancer. ...
Cells minimize this price by sanitizing dNTP pools to limit 6mA incorporation, and by converting 6mA that has been incorporated into DNA back to adenine. Hence, 6mA in nuclear DNA should be described as an epigenetic mark only in basal fungi, ciliates and green algae, but not in animals ...
2) that has been shown to be essential for DNA unwinding in other systems (Molnar et al. 1997). A bipartite nuclear localization signal was also predicted by InterproScan and by the peptide signal–sorting program P-sort (residues 2070–2087). It is interesting that the majority of this ...
