For those of you who are very familiar with Genetics and DNA, You know that Adenine only pairs with Thymine, and Guanine only pairs with Cytosine.
This implies a Double Helix format, as there are only 2 possible combinations. DNA naturally curls up, and resides in the Nucleus of your Cell.
However, me and Griever (thought he deserves a very honorable Mention here) have been talking, and we figured out, that if someone, somewhere managed to force all the Nitrogenous bases to be able to combine with each other (ie: Thymine with Cytosine, Adenine with Guanine) It would be possible to create a Quad-Strand DNA Chain. Now, I'm not asking anyone to break into a science lab somewhere, but what are your general thoughts on this?
