Triple helical structure of dna

WebHere, we provide three lines of evidence that RSC and its isolated ATPase Sth1 are DNA translocases: triple-helix displacement, length-dependent ATPase activity, and enhanced ATPase activity on DNA minicircles. The ability of RSC and Sth1 to displace a triple helix provides strong evidence for DNA translocation. WebIn a triple-helix model (specifically Pauling and Corey's model), some of the van der Waals distances appear to be too small. The initial double helix model discovered, now termed B-form DNA is by far the most common conformation in cells. [11]
