DNA vs. RNA – 5 Key Differences and Comparison

WebActually, DNA is known to exist as a triple strand in rare cases. It isn’t really understood how or why this triple stranded state is used, but during gene regulation this does crop up. I’ll let you in on a secret though: If triple DNA *DOES* exist but isn’t widely used, it means it probably isn’t advantageous in most cases. WebHere, we use triple-helix strand-displacement assays, DNA length-dependent ATPase assays, and DNA-minicircle ATPase assays to establish that RSC, as well as its isolated ATPase subunit Sth1, are DNA translocases. RSC/Sth1 ATPase activity is stimulated by single-stranded DNA, suggesting that Sth1 tracks along one strand of the DNA duplex. ...

Triple-stranded DNA (also known as H-DNA or Triplex-DNA) is a DNA structure in which three oligonucleotides wind around each other and form a triple helix. In triple-stranded DNA, the third strand binds to a B-form DNA (via Watson–Crick base-pairing) double helix by forming Hoogsteen base pairs or reversed … See more Examples of triple-stranded DNA have been found in natural sources with the required structural elements, for example in Satellite DNA.
