In related news, some dude drew a quadruple helix in Photoshop, prompting even more speculation about whether a seven-legged troggmoglophycus could exist in fantasy RPGs.

I may mark all this as offensive because I don't understand it and it makes my brain angry.

I have a tattoo of a double helix on my arm. I won't need to update it any time soon, I think.

This will increase the possibilities of diverse life from being mere infinity to the whopping possibility of infinity!

Soon all twelve strands will be in place.

How much more efficient than 1's and 0's would a quadruple-helix (perhaps with another set of base pairs as well) be in storing data? The quantum hard drive seems like a pipe dream to me, maybe this will suffice.

For all the magnificent diversity of life on this planet, ranging from tiny bacteria to majestic blue whales, from sunshine-harvesting plants to mineral-digesting endoliths miles underground, only one kind of “life as we know it” exists.

Are we sure about that statement? Have we ever been looking for something different from DNA or RNA in microscopic lifeforms? It seems to be very unlikely to have some other replicating molecule on this earth, but it is not impossible (as the quoted statement assumes)

I'm a physicist and engineer. But during my working life its been clear that the 'sciences of the future' has been the biological sciences. I don't think we've yet got close to the revolutionary changes that will come in due course (say, next 100 years).

It is a bit science fiction, and not being an expert I couldn't predict timescales, but imagine when we understand DNA properly, especially human DNA, how to express the genes when and how we like, how to manipulate molecules like PNA, etc.

I don't doubt that we will have complete control over our bodies, and disease, and indeed be able to modify it for the better, over a 100 year timescale. An article like this just shows the foothills.....

How about no helix at all?
Let's build an Alien lifeform from tiny coloured marbles...

Uh, Newsflash? It's not like triple and quadruple helices don't ever exist in nature?

Do they? I'm not a biologist. Tell me more, or give a suitable link. I'm interested.

Surely three strands will make mutation less likely.

It looks to me like the bases on the third strand have a one-to-one mapping with the pairs on the traditional DNA, which means that no new information is being coded here.

The most interesting part of the article is at the end when proposing PNA as a precursor to RNA.

Evilcor,

"Hey, this is totally exciting! This is amazing! This is zzzzzzzzzzzzzz. . . "

Seriously?

I think it's pretty neat. A new kind of life. Let that sink in for a moment.

Plus, it wasn't God this time. Shocker. Alright- now you can go to sleep...

Triple helices involve RNA strands and quadruple helices can be found when chromosomes cross over (hey, I didn't say these things were always stable!). A molecular genetic books would probably be the most helpful. At the moment, I can't think of any links, only of "Molecular Biology of the Gene" of which one of the authors is James Watson (yes, that Watson).
