I'm watching a terrible show I caught broadcast once upon a time that I can't understand how there was more than one season of and also I think if I went looking for fic I would cry and cry and cry and laugh and cry and cry and kill myself.

ETA: What, how is this show this recent? Also, it. I dunno. Whaaaat.

Apparently some TV writers need this explanation, and maybe it will magically reach them if I post it here.

A DNA TRIPLE HELIX MAKES NO SENSE.

Right, look, if you are positing a completely alien life form from another planet whose genetic inheritance is not recorded in deoxyribonucleic acid but in some other chemical structure, then sure, run with it, they have triple helices of whatever the hell that chemical is. They also most definitely cannot have babies with humans, do you hear me, really not, but okay, fine, that's a losing battle, whatever, Liam Kincaid.

Let us return to the completely absurd and impossible notion of TRIPLE-STRANDED DNA.

Maybe some basic background on what DNA actually is would help? See, okay, you probably know that there's four bases of DNA that chain together to make the strands, and everyone calls them T, A, C, and G. (They have full names but seriously, even geneticists call them T, A, C, and G, so it's sort of a waste of time or else proof of giant dorkery to know what they are.) What you may not realize is that this is two pairs of complementary bases. T and A bond together, and so do C and G. This means that if on one side of the double helix there is a T base, on the other side there is always an A base. If there is a C base on one side, on the other side there is always a G.

So imagine you have a piece of a strand which says:

TACGCGTAGCCCTTTA

The strand that goes with it to form a double helix HAS to say:

ATGCGCATCGGGAAAT

It cannot say anything else. They have to match. If they don't match, they don't connect. They don't form a double helix.

This is the really key thing I am trying to get at: the two strands of DNA in a double helix do not contain different information. They contain mirror images of the same information. It's like one side is ROT13 of the other side, except there's only four letters in the DNA alphabet, so it's more like ROT2. Why the redundancy? Because the bases have to be reactive enough to chemically copy when the strand is unzipped, but there needs to be some way to put them away and make them stop reacting when it's not time to copy them, and just slapping a mirror version on makes a stable storage form.

Therefore adding a third strand to a DNA helix--in the first place, what the fuck does it hook onto, the complementary bases are already hooked to each other, and in the second place, it wouldn't add new information, because strands just--don't. All the bases in the third strand would have to complement the bases in the first two strands, which means: same goddamn information.

If you are adding genetic material to an existing multi-celled Earth life form as we know them, just splice sequences of regular double helices into existing double helices (aka, either make the strands longer or replace segments of the strands). If it makes you feel really special, add a chromosome or two (be aware: having extra chromosomes is associated with some odd syndromes). Don't add a third strand of DNA to the double helices, it is MEANINGLESS.

If you are imagining a something superspecial and different from existing multi-celled Earth life forms as we know them, and you want, say, more data compressed into less length of strand, or compress more data into the same length of strand (I'm looking at you, Fifth Element), what you would do is add more base pairs. Why? Think binary versus base 10. What's 36 in binary? 100100. Look at how many more digits you need to convey the same concept, because you only have two options to choose from. But if you have ten options, you only need to use two digits, because you're conveying more information per digit. The more base pairs are available to encode information, the more compactly the information can be encoded. This is something I want to see in my scifi, people. The weird alien species with more efficient DNA whose base pairs are TACGEFLM or something. I would even be willing to buy, for the sake of the narrative, the shocking revelation that so-and-so-supposedly-human has a handful of E's and F's, and even some L's and M's in their DNA and so is SECRETLY PART ALIEN.

But not more strands. Just don't. More strands is more copies. More strands is redundancy. More strands is NOT more information. It is not. And when you say it is, in my head I am converting all of your technobabble to "Magic magic, magic magic, magic magic. Sorcery, what ho!"

Glad to get that off my chest.

Is this one of those things where I don't know I'm swimming in water because I was raised by a geneticist?

I want to make a Girl Genius vid to "Banditos," but downloading all the pages is going to take seriously forever oh my god. But it'll be hilarious? Mistaken and misrepresented identities! Idiots EVERYWHERE why won't they get out of the way.

I want to make a Nanny vid to "A Simple Desultory Philippic," and I will be the only person who ever thinks that's funny, amirite? Also I kind of want to filk/replace part of it, and I don't think I can do just part of it and carry it, and um. Life is hard, yo.

Glee is coming back! When the hell is that? I've been told but I didn't process. [personal profile] traykor and I are making an awesome Glee vid and I should get some stuff on the timeline, ever.

I wanted to make someone a festivids treat based on their dear festividder letter, but I didn't get to due to a combination of factors (the holidays became extra crazysauce family time there, I enrolled in winter session class, I got an extension on my primary assignment and spent several days I would have spent on the treat making my main vid really shine) and now I don't know what to do about that. Do I a) admit that I may never get to that vid without a deadline hanging over my head, b) try to make it anyway in my copious free time, c) stop being coy and say what it is since I'm not making it for an anonymous gift exchange anymore?

White Collar convinced me I should keep working on that vid, I mean it's half done and the show handed me more footage.

And if I make the White Collar vid, I should make the Tru Calling vid to "Madeliene," and let's face it, Tru Calling is terrible brain rot [personal profile] niqaeli will probably watch with me, unlike Nanny.

I am occasionally getting twinges on the stack of Supernatural vids I had wanted to make but I so am not in the fandom anymore so um. We'll see if that ever changes I guess?

So the fandom I'm not participating in?

I totally just figured out who the father is.

I went on a song search re [personal profile] niqaeli's current favorite thing, Sorcerer's Apprentice, and I appear to have instead discovered that across three decades, [artist's redacted]'s snark is a match for [character redacted]'s in an entirely different fandom which I may or may not be vidding for festivids--for a treat if nothing else.
