Here's What DNA Really Looks Like
Рет қаралды 318,131
Күн бұрынThere’s more to DNA than just the double helix we know and love: under some conditions this familiar molecule can take on unfamiliar forms, each of which can have a different impact on our health.

I don't know why I am choosing to fact-check this in the comments, but 1 meter of DNA per cell is the length of the haploid genome. We have a diploid genome, and each cell actually holds 2 m of DNA. Great video!

Every cell knows its time is limited, so it copies its dna to make a new cell before it dies. They copy very very fast. The brain of every cell is a copy machine duplicating the DNA. The exciting part is that humanity doesn't have a stinkin clue what any of it is. Have you ever wondered why dogs can eat raw meat and we can't without catching Ecoli? Have you ever wondered how Rona takes over our bodies, and we can't do anything but the usual to stop it? Have you ever wanted to grow a labrador retrievers head on your hip so you have a permanent emotional support animal? All this is controlled by DNA, and humanity doesn't know 1% of how DNA works

On an educational note: The topic of this video is not "what DNA looks like", but how DNA is structured. This was said in the summary, though I think one has to clarify the title. One cannot "see" the DNA or a molecule in general. We do make pictures of DNA, but those are only representations, but not "the real thing". For scientists, the most important thing about atoms and molecules is how they are structure when they make up matter. When scientists say "that is what molecule X looks like", it is just a simplified expression of "how molecule X is structured". No scientist actually thinks they can "see" or "look" at a molecule... I hope ;)

Many building blocks of life are nucleic acids. Complex carbs, lipids, and proteins as well. DNA may have an acidic PH, but the cell itself maintains a neutral ph, as it has other things that can level out the overall acidity.

'Deoxyribo-' refers to the sugar backbone of the DNA molecule, which is a sugar called deoxyribose. It is called deoxy- because it has 1 less O molecule than another sugar called ribose. 'Nucleic' refers to the nucleobases (the A, T, G, C parts of the molecule) and the reason it's acidic is because there is a phosphate group attached to the sugars, and it's these phosphate groups that help form very strong bonds along the backbone to hold the molecule together. Remember that an acid just means something that can lose a proton (a H atom). When its formed a bond between two DNA molecules, the phosphate group still has an -OH group that can easily lose that H at normal pH, so that makes it an acid. It's not what you'd usually imagine an acid to be like - there's no risk of melting someones face off if you spill some DNA on them!

Omg I have wondered what DNA actually looks like! I knew it didn’t actually look like the models. Thank you!! Thank you!

You should do a vid on what DNA tastes like, for Patreon supporters.

Its probably pretty tasty, disodium 5′-ribonucleotides are a food additive used as a flavour enhancer for extra umami

Ok TLDR: DNA can rotate one way, or the other, depending on whether you are right, or left handed. Sometimes you have a triple strand or 'H' DNA, this stands for 'Handy' and is what ambidextrous people have. There are ten bases in a complete turn, which is why we have ten fingers. Got it correct, right? (little pun there.)

Actually right handed does have to do with hands. When you put your right hand out with your thumb pointing up your fingers curl in the direction of the right handed helix. Right handed rules are everywhere in science and engineering. For all right handed screws (including light bulbs and other threaded objects) if you turn the screw in the direction of the curl of your fingers, the screw (or whatever the threaded object) will move in the direction of your thumb. In physics, you can use the right hand rule to determine the direction of a magnetic field around a wire when your thumb is pointing in the direction of the current. There is much, much more.

Would be awesome if you would do a video on the OMAD diet and or intermittent fasting in general.

Out of curiosity, is there a way of explaining how these processes work _without_ personifying them? If it's because we genuinely do not know how they're done, then that's fine, but I personally find that hearing polymerases "check their work" by "proof-reading" with A-DNA is far less helpful (and far less interesting) than just explaining the actual chemical process.

If all teachers started with what's actually going on then we'd have no scientists today.

2:12 I remember hearing that all of our DNA would stretch (according to Google 2 meters long per cell) across the solar system twice; I used to always think that it was one strand of DNA that would stretch that far, not the combined DNA from every particular cell. Good to know.

I'd like to see more information on "how much information," is in a strand. I thought I read there was 50 million base pairs? If so, this is mind blowing. I'd love to know more.
