    Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they’re good models for understanding how DNA works, but inside of real cells, it’s a whole lot more interesting. Learn why we can’t look directly at DNA, and find out how DNA is actually packed inside cells.

    • @Erith_Idokkel_TheMaceDwarf
      @Erith_Idokkel_TheMaceDwarf 3 года назад +3

      It’s been awhile but i just want to say i think your best bet if you haven’t found out yet is to probably read some science journals that scientists have written and they should explain how they maneuvered it.

    • @luisdiaz1997
      @luisdiaz1997 3 года назад +6

      So the animations of chromatin are not necessarily right, but the input data is from DNA-DNA interactions. How this is done is through a technique Chromatin Conformation Capture (Hi-C), this is done by "freezing" the DNA, then "chopping" DNA using enzymes, and gluing everything back by ligation. Then you can get 2D maps of DNA contacts. You can visualize these maps here: higlass.io/

    I don't get it... What's incorrect about the common double helix depiction of DNA? Or are you just saying that that's not the full story, because it doesn't show the several levels of coiling?

    • @Skoomz
      @Skoomz 6 лет назад +38

      I think they're assuming people think that's how dna exists in a cell. Anyone who took biology would know about the coiling, but i assume they thought most people didn't know about it.

    • @tylerpeterson4726
      @tylerpeterson4726 6 лет назад +16

      Ivar Kråbøl IMO, the worst part about the simple double helix is that it doesn't show the protein globs. Those proteins play an essential role in stabilizing the DNA. DNA does not release from those proteins for very much time. Just long enough to make an RNA molecule. DNA is also quite charged. Without the protein, the DNA might make moving through the nucleus impossible due to the excessive charges.

    • @EliosMoonElios
      @EliosMoonElios 6 лет назад +5

      Double helix is good, he is just using the new data to make a video, in fact there is not need to despise common DNA image.
      Same with the commonly know atom image(solar system-like) nowadays scientist know atom look different but the common image works really well to make scientist stuff because the real atom image is not well know yet and is useless.

    • @markzambelli
      @markzambelli 6 лет назад +7

      Ivar Kråbøl Don't worry... it's the same as saying that a wire, string or wool isn't a single straight strand because it isn't wound into a reel or ball... we know what string looks like whether it's balled-up or not. He even showed his headphone cable... headphone cable is a cable, not a balled-up jumble of knots! The double helix (ie a 'strand' of DNA) is still a very real picture. To me, this vid is pretty pedantic on that score... shoulda been called something else.

      @shayanmoosavi9139 5 лет назад +1

      It's because of the blue light. Animals are hardwired to be awake and alert when blue light hits their eye. That's an evolutionary trait animals gained to regulate their sleep.
      That's how our body knows when to sleep. When we get close to night blue light decreases and the sky will go dark. Then our body will start to produce a hormone called melatonin that makes you sleepy. Blue light however messes with your biological clock and prevents melatonin to form.
      That's exactly why working with a smartphone before bed is a bad idea because it also emits blue light and disturbs your biological clock.

    Cool video! But in the end you left with a very vague conclusion: mirrored DNA is a bad DNA.
    So questions! How bad is a bad DNA? Is it bad because it doesn't occur in nature? If so, why? Or it's bad because it will cause cell to malfunction? If so, how? Do you have examples? If I understand correctly a mirrored version of some molecule has different chemical/biological properties. Is it the case for DNA? Or just its physical arrangement preventing mRNA to correctly copy the data?

      B-ZNA is right-handed. A right-handed spiral is not left-handed. so that there is no left-handed B-DNA is as obvious as it's trivial.
      But why do you tell people who can't know better, that there would be no left-handed DNA ? That's rubbish and every bsaic textbook of melecular biology tells you that. Ever heard of Z-DNA ? You should, 1st semester biochemistry. Does it have biological relevance ? Can biological molecules bind to it ? Sure they can:
      Herbert, Alfken, Kim, Mian, Nishikura, Rich (1997). "A Z-DNA binding domain present in the human editing enzyme, double-stranded RNA adenosine deaminase.". Proc Natl Acad Sci USA. 94 (16): 8421-6
      Herbert, Schade, Lowenhaupt, Alfken, Schwartz, Shlyakhtenko, Lyubchenko, Rich (1998). "The Zalpha domain from human ADAR1 binds to the Z-DNA conformer of many different sequences". Nucleic Acids Res. 26 (15): 2669-72
      Why are you people telling such crap ? Given, B-DNA is the by far most common conformation, but there is a difference between telling "there is none, never ever, it's only right-handed, everything else is wrong and a lie" and "it's mostly right-handed".

    "DNA Doesn't Look Like What You Think!", "Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like." Taken from the title and their own comment. Well they don't show DNA the way that you did because what you are talking about is chromatin, not DNA. Sure it includes it, but you can't use the two terms interchangeably. That's why you will never see chromatin as DNA in biology textbooks. So what I leave you guys with is AMERIKA EXBLAINE!

    Actually that whole "bad DNA" thing is not true. It is true that most DNA is found in a right handed spiral, but left handed spirals also exist. There are three biologically acitve forms of DNA (A-DNA, B-DNA, and Z-DNA). Both A and B variaties are right handed spirals, but Z-DNA is a left handed spiral. And it actually plays a role in RNA editing by interacting with certain enzymes.

      Yeah, you’re right but you have to consider that Z-DNA isn’t as “regular” as B-DNA. I mean, when u search for picture of DNA (like the image he shows us in the end) what u will look at is B-DNA’ s pictures, so it is incorrect to draw DNA with left-handed helix.

      A more accurate for RNA, might be a flash drive, since it not only stores genetic information, but can transfer it as well. This is, of course, my rudimentary understanding of it.

      @warrenmcdonald8170 6 лет назад +32

      I was thinking something similar Brandon. It seems odd that every time we look closer at life, it gets more and more complicated. And yet some people believe that these insanely complex system that build more insanely complex system, that build even more insanely complex systems, can all be created and function purely by accident. And not just one accident, but millions of accidents stacked upon millions of accidents. It's like believing that if you roll a 20 sided die 20 million times it will come up a 20 every single time. And then saying that it's no big deal and probably happens all the time. Maybe it's just me, but if I found a nanobot that was microscopic, could self replicate, and build a fully functional robot trillions of times it's size, I would think there was something more involved than just random chance.

      Is this a reference to the concept of gender as a social construct? Because gender _is_ a social construct. When someone says they were born male but identify as female, that does not mean they believe that their DNA is an illusion or that their DNA is subjective. There's no denying what your chromosomes are. However, there's plenty of room for disagreement on what those chromosomes should mean about your station in life.

    Our whole universe was in a hot, dense state

    Neanderthals developed tools
    We built a wall (we built the pyramids)
    Math, science, history, unraveling the mysteries
    That all started with the big bang! Hey!
    Since the dawn of man is really not that long
    As every galaxy was formed in less time than it takes to sing this song
    A fraction of a second and the elements were made
    The bipeds stood up straight, the dinosaurs all met their fate
    They tried to leap but they were late
    And they all died (they froze their asses off)
    The oceans and Pangea, see ya wouldn't wanna be ya
    Set in motion by the same big bang!
    It all started with the big bang!
    It's expanding ever outward but one day
    It will cause the stars to go the other way
    Collapsing ever inward, we won't be here, it won't be hurt
    Our best and brightest figure that it'll make an even bigger bang!
    Australopithecus would really have been sick of us
    Debating how we're here, they're catching deer (we're catching viruses)
    Religion or astronomy (Descartes or Deuteronomy)

      Some do. And there is a good reason to think about how it looks. Without trying to figure this out then we would not have figured out the basic coding mechanism of DNA. It would still be bits of mysterious strings to us. By getting a clear and clear picture we and understand how DNA code for things which in turn lets us find new cures and use bio engineering to solve our problems.
      Personally, I see this just as atomic models. There several. Some more accurate than others. Sometimes a less accurate model might be actually more useful as it helps you build an understanding of the fundamentals before you dive deeper. So even if the Bohr model of atoms is less correct then atomic orbital model it still has it uses.
