Triple strand helix

WebOct 27, 2024 · In terms of direct RNA-DNA interactions, two kinds of triple-stranded structures can be formed: R-loops consisting of an RNA:DNA hybrid and a looped out DNA strand, and RNA:DNA triple helices (triplexes), in which the RNA binds to the major groove of the DNA double helix by sequence-specific Hoogsteen base pairing. 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 triplex DNA structures.

Each of these helices shares the same axis, but they do not take up the same space because each helix is translated angularly around the axis. Generally, the identity of a triple helix depends on the type of helices that make it up. For example: a triple helix made of three strands of collagen protein is a collagen triple helix, and a triple helix made of three strands of DNA is a DNA triple helix.
