The fluff states that the Eldar DNA is made of 3 elixes instead of the regular human 2 elixes DNA. You may think that triple elix DNA is pseudoscience bullshit (like: "hurr durr, let's give the Eldars an other DNA elix, moar is better") but it actually exists and it's called DNA triplex and it is formed with non conventional DNA base pairing. It is thought to have a role in genomic regulation and some reserches are thinking to use it in genetic engineering. This particular DNA structure isn't as stable as the 2 elixes at physiologic pH (~7) but it is more stable at lower (more acid) levels of pH, suggesting that Eldar blood might be acid, or at least more acid then human blood. What do you think about this, /tg/?
I wasn't thinking about weaponizing it, I just stumbled across real life DNA triple/tetraplex and I thought about wh40k and Xenology. My best conclusion it's that it could not be as acid as metal melting acid, but it could mean that Eldar blood might taste as vinegar or lemon
>using science in 40K
Space marines eat brains to absorb memories. It's not even a psychic scan thing, they actually have to chew, swallow and digest before any information is gained.
The short answer to everything is "the Emperor wills it", and the long answer is "the Emperor wills it" followed by a bullet to your head.
>This particular DNA structure isn't as stable as the 2 elixes at physiologic pH (~7)
Doesn't triple-helix DNA require a specific stabilising agent to keep the axis from exploding?
Yes, science and wh40k usually don't go well together, but Xenology was kind of science-based and I liked the way they described alien anatomy
Maybe they taste like vinegar veggy mushroom soup?
This non conventional base pairing is called Hoogsteen pairing and it's favourited by the presence of protonated nucleotide residues that are more stable and frequent in acid environment
I've never eaten bugs, but in some countries they eat stuff like fried grasshoppers, I guess they would taste like a acid mixture of that and chicken.
Everything tastes like chicken
I imagine you'd have to be very careful, as knowing the tyranid hive mind, it'd probably make tyranids inedible just to piss off anyone who tried to use them for resources.
Only tyranids are allowed to eat tyranids!
>Be Imperial citizen

If tyranids meat is actually good it could be a good propaganda to get more soldier to fight them better.
>Hey, you! Imperial Guard, are you tired to eat the same shit every day? Then fight those fucking xeno scum and you are going to eat like a king!
>Eldar DNA is tripled helix as per image
>Image shows 4 helices
Counting is an important life skill
Regardless, the quad helix DNA doesn't even make any sense. Its basically two different chromosomes looped together to look cool.
The whole purpose of the double helix is to allow copying, you split it down the middle and then attach the missing matched parts on each side. If you add additional helixes they do not serve any purpose whatsoever and they do not actually improve things in any way at all... except for unnecessarily complicating things and making it more difficult to physically fit shit around it.
Also, triple helix doesn't make any sense because they can no longer be matched. A-T G-C are the matched pair
If you make it triple... then what are you putting on the third strand? it will either be a copy of G or a copy of C. but then you are not matched at all.
Of course you could have a completely different set of letters... but then it isn't DNA
The fuck you're right, I really thought to be sure about the number 3... That's a big mistake
However an eventual third strand has some purpose: genomic regulation, activating and deactivating some portion of DNA during transcription
Btw I re-read the Xenology page about Eldar DNA and the helixes are 5...
Well Ambull which is an insect like beast is a delicacy in the IoM. So eating nids if they aren't toxic wouldn't be that unusual for people in wh40K. I'm guessing many of them have actually eaten weirder shit.
It's not DNA. That's the point. It's whatever better building block the Old Ones used when they created the Eldar and the Orks. It may have some similarity to DNA, but that doesn't mean it is.
I think it was in 15 Hours where they are sitting around and the short guy (can't remember his name) talks about when he was fighting along side some Catachans who'd caught and kid a dino to eat and told him to fuck off because they weren't sharing so he called in an artillary strike and bagged one that was killed in it.
Then of course there was another story in the Omnibus about catachans on a death world and how they immediately start identifying what they can and can't eat.
I think then it's not just Eldar blood that would have to be acidic but the entire Eldar themselves. Us humans are set to be around neutral pH with some pouches of acid here and there (like the bladder and the stomach). A DNA is coiled in the nucleus, and said nucleus works into a cell. Since they have DNA, it is safe to assume that Eldar are a cell-based lifeform. Now the problem is that the lipid membranes that form our cells also depend very strongly on that equilibrium for transmitting electrical impulses. Those electrical impulses are nothing more than ions (kations, anions) transiting across channels. Muscle contractions, thought, all of those things depend on the fragile acidic equilibrium of our bodies. So Eldar are more acidic as a whole, or they have very unstable DNA.
The other option, of course, is not to make Eldar acidic but to leave them with their unstable DNA. However, they'd have a much better, safeproof way of replicating than our wonky system. Or, looking to their longevity, their cells last a lot longer and don't need to replicate as often as ours, lowering the need to replicate the DNA, and thus it can stay all coiled and protected. Having a problem uncoiling, replicating DNA and creating new cells could be used to explain the low Eldar fertility rate (producing less gametes).
TL;DR version: either the entire Eldar is slightly more acidic, not just the blood, or the cells don't replicate as often.
It is called "Eldar DNA" and the analysis have been made by a magos biologus, so it is definitely a Deoxyribonucleic acid, this means that the backbone of the molecule is the same of our DNA, the deoxyribose sugar linked to phosphate groups and nitrogen ring bases. In Xenology it is stated that the strands of the helix are 5 instead of 2 and the nitrogen bases are 20 instead of 4 (A T G C)
I have several problems:
quintuple DNA, but which strands carries the actual information? In human is it double DNA but only one direction gets translated into mRNA and into protein. So either 3/5 or 2/5, but probably 3/5 or else you'd have a redundancy.
Secondly, 20 bases, assuming they are grouped by three, gives a MASSIVE number of codons, so either Eldar physiology also works with a much bigger number of amino-acids to construct protein, or there is a lot of redundancy. Assuming the first, the Eldar would need to eat very different things than we do, however what humans and Eldar eat seems to be sort of similar (they can survive on the same planet before Vulkan crisped them all, meaning that biotope works for both.)
Obviously, being superior everything, you could simply say they synthetise all their amino acids from others.
Regardless, if we still go with the "built with massively different proteins", I really do wonder what Eldar would taste like.
Well since it actually exist irl you're argument is invalid, but do let me say that the OP arguments is also invalid cause hell if the freaking people at GW give a damn about anything it's freaking FICTIONAL don't look for hiding meaning where there is none.
You OP look like the freaking Language teachers, what was the author trying to say with this, well guess what most of them what's fucking writing not some hiding agenda with a gazilion layers.
Half Eldar are canon? Never heard about it. I believe that one of the reasons of the over numbered helix was to make eldars and (for example) humans not able to make hybrids
As long I believed the strands were 3 it kind of made sense, but with 5 it's harder
About the bases it's definetely fluff bullshit (moar is bester) if they didn't mean to talk about something like our less frequent bases or the methilated bases, in that case it makes sense in a epigenetic way
Kek, I wasn't looking for hidden meanings, it's just a flavour fluff thing
It's thinking that a thing in the 40k universe might be made in that way, and that the fluff writers (very probably unintentionally) wrote something that scientifically speaking might hace sense
Retconned to make the 40k less fantasy looking (half-elves)? Just as (if I recall correctly) in the past there were female ork and the ork race reproducted sexually and then they made them fungi-plant-algae-mammal mix in order to give them a more sci-fi fluff
Xenology is full of bullshit. Nothing found therein should be taken as surprise nor fact.
Yes but Xenology is considered an unreliable source within the setting that already is filled with unreliable sources. Its like, super unreliable. Its the cheap printed tabloid rag your aunt keeps buying at the check out line tier of reliability.
>look at picture
>it's actually a quadruple helix
God damn, get it right GeeDubs
That DNA doesn't connect...
>Elder are actually two different species connected on the cellular level
>The reason their species can't breed anymore is because they've become immune to whatever it is that fuses the DNA together for breeding.
