Triple Helix: Designing a New Molecule of Life

WebAn RNA triple helix consists of three strands: A Watson-Crick RNA double helix whose major-groove establishes hydrogen bonds with the so-called "third strand". In the past 15 years, it has been recognized that these major-groove RNA triple helices, like single-stranded and double-stranded RNA, also mediate prominent biological roles inside cells. WebIts polypeptide sequence would be able to be deduced from the nucleotide sequence of the DNA molecule that serves as the gene for the protein. The triple helix structure of collagen protein is possible largely due to glycine and its small side chain. Which statement about the Miller-Urey experiment is correct? fabysimaooficial

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.
