#SciShow
Scishow: Microchromosomes are half of the chicken genome.
Me, narrowing my eyes at my chickens in the backyard: What. ARE you?
Scishow: It's not birds that are weird, it's us.
Me, staring at my shaky microchromosomeless hands: What. Am I???
So if you get half a chicken, is it all from microchromosomes? Then it would be possible to breed half-chickens.
🤣😂
Maybe this is why so many things taste like chicken =p you know im right..
God made and sustains everything. He is the most important Being in the universe.
12 drummers drumming, 11 pipers piping, 10 snakes and lizards, 7 types of birbs, 3 different mammals, and a modern relative of early vertebrates.
Thought the same 😂
Birb is the word

Dam perception, now that's all I hear him say!
I really like this. I feel like scishow has been stepping up their game recently.
Hank Green = good Scishow episode
I firmly agree
I think it's been consistently good since it started
Scishow always makes my day better.
Word
Same.
Its become apart of my wake up routine, I make a cup of coffee and watch some SciShow.
Same! Always one of the first things I do when I get home at sit back to relax after work. Brew some green tea and load up the new scishow vid then fall down a random science rabbit hole thanks to the video
I think this very topic demonstrates that just because we don't know what it codes for yet, doesn't mean there's a such thing as, "objectively proven", so called, JUNK DNA, in any Genome.
"Junk DNA" doesn't mean we "don't know what it does". It just means it's non-coding. Not making proteins because it's not between a start codon and a stop codon. It's true, however, that there are likely unforeseen functions to non-coding DNA.
@@newq When we observe and if it doesn't do anything now, but if it might've done something in the past or is gonna be functional in the future, it is pretty much "We don't know what it does".
@@gsreads You're right. I worded that poorly. I was mostly just a little annoyed by Bryan's overly dismissive tone based on a misunderstanding of what "Junk DNA" means.
@@newq I wasn't trying to be "overly dismissive" of anything, nor do I have a "misunderstanding" of what junk DNA means. I know what you said is true, technically... But I also realized the very thing that, Gautaman S, said. (Which I don't feel like re-typing out.) That's all, and it's why I put "objectively proven", in there... I know the technical stuff, it's what I studied at University. I'm not trying to be a jerk or anything, just giving my opinion like everyone else. So, I'm sorry if you took me wrong, if it's gonna trigger folks...guess I'll delete it then, not worth the trouble.
@Fk Yu Yeah that's so true! I totally agree with you. I read it, over and over, and I can see where the OP comes off a little bit dismissive, I gotta admit that to Nick Warren!
I never intended that to be, that way tho, I just realized that the "junk" could've or probably would've coded something, at some point, history or future... Our codons can mutate and shift over the generations, proven by many examples, but the animals of the same species, in separate environments, but development of radically, separate, physical traits. Such as "cave fish" species's (didn't look up the kind). It's just what comes to mind... We don't know what the code is and/or was or maybe for. As someone who has some experience with it, it's very intriguing to me... That's why I said it in the first place, lol. Just my opinion, like everyone else man. It's cool if nobody else agrees with it, cuz it's mine.
Anyways, Blessings to you and yours this, hopefully, better New Year!
Hank has a face of pure science-learning joy when saying "WRONG" in the introduction
Wait, so that "lint" was actually microchromosomes. And mammals don't have them.
So how do you explain dust bunnies?
Dust is mostly made of dead skin cells
@@victorvonsteuben1728 so dust bunnies are zombie? 😂🤷🏼♂️
@@seanfox3007 exactly
@@victorvonsteuben1728 i heard that this was actually debunked
@@nya8482 sorta. it turns out it depends on how you live.
"there's a platypus controlling me, he's underneath the table"
So it's like if big chromosomes are built out of Legos, other vertebrates you can see the Lego bricks in the DNA. But in mammals our Legos were melted together so it looks like a solid piece instead of seeing the lines of the individual bricks.
Wow, this is really incredibly interesting! I've gotta go look into this some more!
The fact that the list of animals didn't end with a partridge in a pear tree is a little disappointing.
I recall reading that foxes have microchromosomes - which is thought to be one of the reasons they are so adaptable.
Thank you! I will now eat all lint to become superhuman.
So does this mean it'll be easier or more difficult to cross a chicken with a cow?
I already know you can't cross a chicken with a road.
While mammals may be weird within the chordates for having megachromosomes, chordates would be considered weird within the eukaryotes and megachromosomes seem the norm in plants and fungi. Bacteria and archaea don't have enough genetic material in total to have a megachromosome at all.
Some people talk like the science of DNA is complete and we know all there is to know. Nice little reminder that those people are silly
I feel like the fact that they're not called "michromasomes" is a huge lost opportunity.
But they ain't yo chromosomes.
*our chromasomes
F for "michromosomes"
This has been one of the more interesting videos as of recent where I actually learned something new. This could definitely help us deepen our understanding of genetics and might lead to some interesting results.
A micrometer is an instrument. A micro-meter is a unit of length..
Say it right, frenchie!
All this shows is just that we mammals are simply cooler and more Xtreme than other lifeforms.
Too bad, we can't find a non-mamalian researcher to get a differrent opinion✌
It always amuses me to hear non-Aussies pronounce "emu" :) Hot tip: Say it like "e m-you", not "e moo" (just realising how hard it is to write pronunciations...).
Like the “eem “ sound in meme ? Then you ? Or would the m sound go more towards the you part Like e-mew
@@justxaine.3544 That's a great way of putting it! "eme-you" or "e-mew" both would work, as there isn't really a gap between the two sounds; it all melds together in a drawl.
"just realising how hard it is to write pronunciations..."
Especially in english! Bed rhymes with head, bead rhymes with need, and lead can rhyme with either.
Thx for that!! I always wondered how to say it right..🤶
I've always said it as Ee-mew, as an American.
Nothing can satisfy a person better than discovery.
huh, so that's where my missing chromosomes went
Very nice show! I love it! Keep up the good work.
Interesting information. Based on the speed of your delivery, I suspect that you are well caffeinated.
He is almost always like this, but to be fair, when he does one-on-one interviews he has a slower speed.
FYI: The word is actually *minuscule,* etymologically related to *minus*. (Hey, write a show expressly for nerds, and... )
"a mammal with microchromosomes?" *puts on hat* you know the drill
This confirms my theory of genome evolution. I have discovered and have verified 95% of how complex life evolved and emerged, and have discovered a few additional factors for how life emerged on Earth. I need funding to confirm and verify the final 5% so I can publish in science and medical journals. With years of searching, I cannot find the funding I need to complete the research. Someone has to know someone that can fund the research. I have fully funded the research until now. Injuries from a car crash have depleted my funds. L Davis hit me at about 35 MPH while I was stopped for a red light.
This is probably unrelated but it's what's on my mind. My mom is 50% Greek but I'm only 4% Greek. Freaking how. She's my mom, the DNA test inadvertantly confirmed that too. I didn't think otherwise. But how do I not have more Greek. 4% of 50% seems wildly low for a parent to child.
Mammals are also weird because of live birth. A few egg-laying animals also have, through roundabout ways, live births, but mammals are still in the minority. The majority of animals lay eggs, and then the offspring will hatch from those eggs, outside of the mother's body. But hey, our metabolism allows us to be some of the fastest (on land), strongest, largest and smartest animals on the planet. Mammals rule!
@Fk Yu True! I just wanted to clarify that while some birds can fly faster than any mammal can run, on land (and in the sea) we still get the gold medals.
So the lint wasn’t lint, and mammalian DNA is way less straight forward than modern dinosaurs, the humble chicken. Cool. Happy Holidays!
I KNEW THE PLATYPUS HELD SOME SECRET
Between Hank Green and Simon Whistler, i think im ready to retry college!
(Not really though... XD)
Happy Holidays everyone.
So here I am being here for 1 week I think this is best channel I was looking for my interesting topics to listen love sci show
So this is how dust bunnies grow.
So.... I'm breathing CHROMOSOMES? Aaaack!
Baby chromosomes are the ancestors of the mega ones.
Always clean the lint from your dryer. It's a hazard.
don't know Y this is Xciting
👍😄
So basically micri-chrosomes are like these pop hits CDs from the ninties that you never listen to and yet not throwing them away?
"Minuscule chromosomes "😂😂😂
A lot of my chromosomes are hiding in a sock
Wow, this is really interesting.
So, there are large amounts of DNA left over from the evolutionary process that is unused in many mammals and birds. Transcription factors help tell the polymerases what segments of DNA to read. Would it be possible, if scientists were able to alter or manipulate the transcription factors into favoring ancient DNA that we could turn a chicken into a T-Rex if it were able to locate enough viable microchomosomes?
Oh. I thought they were talking about the lint in my bedroom. **cough**
"Muh chromosomes"
"8th grade biology book"
wow - i love when i find something on the net thats genuinely new!
I wonder how much is in my belly button fluff........
Love your channel, but must strongly suggest you pronounce it micro-meter, not mi-crom-e-ter. The "ometer" pronuciation is for measuring devices, like speedometer, odometer, barometer, thermometer, and yes micrometer. Mi-chrom-e-ter is a device that measues small lengths. Micro-meter is a millionth of a meter. The kil-om-e-ter mispronunciation battle is lost, mostly I think due to popular sci-fi TV shows, but I will continue to pronounce it kilo-meter. (We say kilo-gram, not ki-log-ram). What would be next? Mi-lim-e-ter and cen-tim-e-ter?
Oh Hank I hate to say this. I really do. But ... 0:28 you have "miniscule". One of the most commonly misspelled words. It should be "minuscule".
We all share magnesium and potassium etc,etc,etc. so that’s why the frog is my cousin.
Thx for uploading!!
Mammals are really weird due to 200 million years of genetic bottlenecking. Only 2 cones, no diurnal mammals, no pigments other than melanin and sometimes rust...
Another example showing how much we truly don't know.
El problema es si son trozos de datos dispersos específicos en la célula que no se han podido estudiar, podrían ser desde residuos a partes de complemento a la hora de leerlo, no me extrañaría tengan investigadores por partes de la célula como piezas de relojería.
I loved this video! And I almost didn't watch it because of the title.
Erk: at 0:28, "miniscule" for "minuscule". Now I realize English doesn't care (as Wiktionary put it, "Miniscule" was originally a misspelling, but now so common that it has come to be considered an alternative spelling by many"). Even so, I cringe.
Posing a hypothesis based on one animal? Hmmm, I see.
Oh wait I think I heard this joke before. Then the priest walks in and said to the chromosomes, "I said see you at Lent, not lint".
So, this is all about what we don't know about micro-chromosomes. How does U-tube make money by not uploading craps.
I'm going to be funny today it's not a platypus it's a beaver duck ha-ha
lol just when you think we know all about something, nope!
Wait did he just say insects were vertebrates at 1:44?
I love how hank runs the show now but I actually only subbed this channel for the sexy guy with long dark hair 🤓
Micro chromosomes are proteins , antibodies, prions lots of fragments in DNA. Possible chromosomes become cells after protease, considering asexual and sexual reproduction determining whether the daughter cell will divide or not not dividing the cell could migrate to become a cell that divides and is regulated or after maturing divide or phagocytos into a organ and lose its membrane, cells become part of a system or a collective, in a leaky blood vessel when the vessel membrane becomes damage necrotic cells escape occurs Possible necrotic cells are delivered by cells through the bloodstream reinforcing the epitheliam
The smaller they are the smaller their Chromosomes.
Then elephant DNA must be the size of fists.
So fascinating.
So, Michromosomes or Chromosmols ?
Very informative video. Watched to the end. Noticed that Hank was the Executive Producer, and the....Hank? Shouldn't that be Host? Oops, need to QA the credits at the end...
3:32 or animals evolved from humans as the genes became more survival specific.
I finally found my friends lost chromosome
We are also modern relatives of early vertebrates
"Junk DNA" isn't junk.
No. Wrong. That could become a meme easy
"Junk DNA" epitomises why humans won't be able to decipher Alien messages. We can do better!
UA-cam will definitely keep my birthday interesting!!
You're Jesus?

Papa Franku likes this episode
imagine calling them microchromosomes and not micromosomes
merry christmas
Feels like not going with "michromosomes" is a real missed opportunity.
Huh
I wonder if mammals get more cancer than birds because our chromosome structure. (at least credit me if you steal the thesis lol)
Did you change the title and thumbnail?
Chromosomes... word count... 😄
So this is why so many things taste like chicken =p
Did you say fishes...
Wow pretty scary stuff ! but so interesting !
Absolute Truths?
Maybe that's also how viruses came to be?
I was just thinking about viruses and how they came to be yesterday.
I think this an interesting theory.
It could very well be. Virus immunity helped to improve and build our own DNA through manipulation of our rDNA (or RNA can't remember) by restructuring the chromosome to benefit the cell. Viruses are very old and thrive off of animals, so they both are closely linked.
Lancelot?
if i eat them will i get extra chromosomes
smol chromosomes
My take away is my belly button can spawn life
What if mammal micro chromosomes are just extra micro??
Wow!
Ok, can this help us make dinos?
1:57 Chinese soft-shell turtle, I think
so thats why this channel has so many "extra"...
It's pronounced micro-metre, not mike-rohm-iter. A mike-rohm-iter is a measuring tool, like a thermometer, or speedometer, or manometer...
3:20, what's an emoo?
Digital bovine? IT cattle? ...jk 😅
