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 Hoogsteen hydrogen bonds.
Norman Simmons (1915–2004), US DNA research pioneer, who donated pure DNA to Rosalind Franklin in the prelude to the double helix discovery; Piotr SÅ‚onimski (1922–2009), Polish-Parisian yeast geneticist, pioneer of mitochondrial heredity; William S. Sly (born 1932), US biochemical geneticist, mucopolysaccharidosis type VII (Sly syndrome)
A DNA triple helix is made up of three separate DNA strands, each oriented with the sugar/phosphate backbone on the outside of the helix and the bases on the inside of the helix. The bases are the part of the molecule closest to the triple helix's axis, and the backbone is the part of the molecule farthest away from the axis.
Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount are unique to us, making us about 99.9% genetically ...
Pauling then proposed that deoxyribonucleic acid (DNA) was a triple helix; [60] [61] his model contained several basic mistakes, including a proposal of neutral phosphate groups, an idea that conflicted with the acidity of DNA. Sir Lawrence Bragg had been disappointed that Pauling had won the race to find the alpha helix structure of proteins ...
In 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. [12]

Non-B DNA can be classified into several types, including A-DNA, Z-DNA, H-DNA, G-quadruplexes, and Triplexes (Triple-stranded DNA).. A-DNA is a right-handed double helix structure for RNA-DNA duplexes and RNA-RNA duplexes that is less common than the more well-known B-DNA structure.
