On the Earth (and in the Internet) you can find a Triple Helix DNA...
It consists from a normal (2)Double Helix DNA where is added a partial third (1)simple Helix: 2+1=3.
By my Idea:
On the core of the Double Helix DNA 2 Bases X-Y make 2-3 Hydrogens Bonds with each other...
On the core of the Triple Helix DNA 3 Bases X-Y-Z make 3 Hydrogens Bonds with each other!!!...
On the Triple Helix the Bases are Double-Bases because each Base has 3 Hydrogens Bonds with each of the other two Bases!!!
By AB, CD and EF are the 3 Hydrogen Bonds which connects the three(3) Double-Bases...
The Bases X(BC), Y(DE) and X(AF) do NOT mach together in any other way, with 2 or 3 Hydrogen Bonds...
They also do NOT much with themselfs...
This Molecular-Model of thisTriple Helix DNA fulfills all the right conditions!!!
Namely, if you know the ONE Base - and its orientation - you also know which are the other two Bases!!!...
(Because there is only one way to join them together!!!...)
So, when the Triple Helix DNA is replicating itself... it creates - instead of two copies - three copies: 1>>>3
This Triple Helix DNA can also be used to store Information Like the Double Helix DNA !!!
The IDEA of this Triple Helix DNA is very interesting...
However it is a more complicated Model as the Double Helix...
It is more difficult to Transcript in m-RNA and to Translate with t-RNA into Proteins:
The Triple Helix DNA = 3/3 Bases...
Then:
or m-RNA = 1/3 Bases and t-RNA = 2/3 Bases
or m-RNA = 2/3 Bases and t-RNA = 1/3 Bases
But it could be possible to exist in the Universe...
