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. Hoogsteen base pairing A thymine (T) See more Triplex forming oligonucleotides (TFO) TFOs are short (≈15-25 nt) nucleic acid strands that bind in the major groove of double-stranded DNA to form intramolecular … See more Triple-stranded DNA structures were common hypotheses in the 1950s when scientists were struggling to discover DNA's true structural … See more Genetic instability Considerable research has been funneled into the biological implications relating to the presence of H-DNA in the major breakpoint regions (Mbr) and double-strand-breakpoints of certain genes.

WebJan 20, 2013 · Today, the pair's modern counterparts in the university city continue to work on DNA's complexities. Balasubramanian's group has been pursuing a four-stranded … WebDouble-stranded DNA is an antiparallel molecule, meaning that it's composed of two strands that run alongside each other but point in opposite directions. In a double-stranded DNA molecule, the 5' end (phosphate-bearing end) of one strand aligns with the 3' end (hydroxyl-bearing end) of its partner, and vice versa. WebTherefore, any DNA strand normally has one end at which there is a phosphate group attached to the 5′ carbon of a ribose (the 5′ phosphoryl) and another end at which there is a free hydroxyl group attached to the 3′ carbon of a ribose (the 3′ hydroxyl). ...
