Our bodies are made up of organ systems, which are collections of organs. Our organs are made of tissues, and our tissues are made of cells, and those cells are made up of nonliving things like water, lipids, and proteins. And each of our cells make proteins that do different jobs in our body.
The pigment that makes your eye color is a protein. The keratin that builds your hair is a protein. But you also need to build proteins for a normal physiology, so you have instructions for proteins like antibodies and enzymes in your genes as well.
And we have approximately 25,000 genes in our bodies. Each of your genes holds the genetic instructions that tell a cell how to make a specific protein for a specific purpose, and in this episode of Human we find out exactly how that process works.

Is eye color determined by genetics?
ghr.nlm.nih.gov/primer/traits...
“Eye color is determined by variations in a person’s genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.”
Deoxyribonucleic Acid (DNA) Fact Sheet
www.genome.gov/about-genomics...
“Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.”
Ribosomes, Transcription, and Translation
www.nature.com/scitable/topic...
“The genetic information stored in DNA is a living archive of instructions that cells use to accomplish the functions of life. Inside each cell, catalysts seek out the appropriate information from this archive and use it to build new proteins - proteins that make up the structures of the cell, run the biochemical reactions in the cell, and are sometimes manufactured for export.”

Hey SEEKER! I want you people in my college 😭😭😭😭🙏🙏🙏🙏 you people explain these concepts so well. I love you💝
This is the best explanation of DNA that I’ve come across on TH-cam and I’ve watched many tutorials and am still struggling to grasp the entire concept so thanks for excellent teaching skills!

So incredible. Thanks so much!
This channels videos are one of life's pleasures.
The creme brulee analogy seems broken. Creme brulee doesn't make itself. Also, this perpetuates the myth that genes neatly describe a set of instructions that can be understood like a recipe (i.e. this is the gene for x kind of thinking).
For an example, fur color and disposition seem to be linked traits in foxes. The protein that controls fur color also affects brain structure. This is not a result that would be at all predicted by the recipe analogy.
I don't know that our culture currently possesses an easily digestible analogy that neatly captures complex self-organizing systems in which a bunch of tiny rules interact in very complex ways for a variety of unpredictable and surprising results.
But the description of transcription is nifty. One other really nifty thing to know about ribosomes is that they are made of RNA and protein, not just proteins like most of our molecular machinery. It suggests an abiogenesis in which RNA played a significant role, since ribosomes are so fundamental and universal.
Ok boomer
@@FlashBO7 - Did you mistakenly reply to the wrong post or on the wrong video?
Eric Hopper no I mistakenly reply to a wrong person
true! One problem with analogies is that they never perfectly represent the subject matter, only view it through a more simplified and distorted lens. Unfortunately, making the analogy any more complex for the sake of accuracy would hurt its effectiveness in transcribing the meaning to a larger audience.
You said whole lot of nothing in this essay. You contradicted yourself multiple times. You don’t understand biology. At last, okay boomer.
5'TTAGGG3' is TELOMERE
How ??
Awesome analogy + animation
I am so glad other people study this and understand it. I was lost somewhere around two minutes in. Very happy to know that others are on top of it. This frees me to concentrate on being a musician for a living. I wonder if my DNA consists of a lousy ability to understand DNA, but then also a great ability to play a 3 over 4 polyrhythm in a minor Blues scale, and modulate one half note up without missing a beat.
He explained it very poorly
repeated TTAGGG sections are telomeres, they influence how often a cell can divide :)
Thank You Seeker! I've been watching since the DNews days, love learning from all of you.
Same.. DNews was always an unfortunate name
I would really like to know , how DNA encodes 3D data of body shape , I already have some hints about it , like cells use Cilia protien on their membrane to know their 3D position , and cilia does some singnaling that interacts with the DNA , but it would be pretty cool if we know how DNA encodes topological data , thus we can tell how some organs can endup malformed

I already knew most of this through school but it's still astonishing how it all works in the background with no "brain" organising it. The CRISPR machine blows my mind.

Saaaaame mate
This video brought back so many good memories of junior year IB biology for me 😂❤️
Thank you so much for this ❤️ 💚 👏 👍
Interesting topic. Excited for the new video
Wish to learn and improve my channel!
Bravo and thanks a lot
I get lost with all the abstract explanations and terms and how they relate to each other. I will never be a medical professional or scientist. Still , I have always tried my best to get a basic understanding of the universe around me. I have always been fascinated with things I know nothing (or exceedingly little) about. Your videos touch on these basic/complex concepts and feed my curiosity to keep looking for more. Thank you !
You guys forgot to mention that the RNA, which is created right after the RNA polymerase finished it's job, is actually the pre-mRNA. The introns (non-coding parts) get removed in a process called splicing. Afterwards, a Poly-A tail gets added to the 3' end and a cap-region is added to the 5' end. This is important because the mRNA would be disassembled in the cytoplasm without the Poly-A tail and the cap region.This only applies to eucaryotes though.
Thanks a lot sir💓
Maaaaaaaaaaany thanks Patrick. This was a great video.
Super explanantion!
I recently watched Unnatural Selection on Netflix, genes are just so amazing! It's a bit scary what CRISPR is capable of, but still facinating. Thanks for the video!
7:52 Well played
Since these are too small to see, how do thay figure all these mechanisms out? That would make a very interesting video.
Thankyou sir !!!! Now only i understand about DNA .....
I haven't heard a better explanation then this.
My favourite case
I'm still waiting for you to tell us how DNA instructs cells to form an eye - as you promised at the beginning of the video.
The DNA polymerase doesn't separate/unzip the DNA strands, a protein called Helicase does that.
More DNA content please!
dont forget to add in a mix up of some COSMIC RAYS with gluons that tend to interact with RIGHT Handed particle configurations.
Yall broke this down so well schools should be taking notes😂😂😂
the explanation is detailed yes but how do these polymerase and ribosome know what to do. what is triggering their reaction?
Freue mich schon richtig auf die Koch Videos mit den Jungs von Pietsmiet!
Also a Ttaggg is a 'telomere', whose real word equivalent at the end of a shoe string is called an 'aglet'.
I don’t understand how macro evolution could explain how all these molecular machines could have arisen at the same time and had such complexity to create all the systems in a organism. The more we uncover, the more it seems to me that we have precise and highly tuned coding that points to intelligent design, whether that be hologram theory or being fearfully and wonderfully made by a creator. But I don’t think those two are mutually exclusive scenarios, could be the same thing.
Our world never ceases to amaze me whatever the case.
PS- these are just my thoughts, I know everyone has their own. And I respect that. Have a great day awesome people
There is no evidence supporting the existence of a creator. What created that being?
Appearance of design does not mean it has a designer. With evolution what remains is what we see today. It surely did not start as well “designed” at first. Most of the primary cells that ever existed never evolved passed unicellular stage. Scientists are pretty sure only one cell actually ended up creating every living thing we know of. What appears as intelligent design is just a byproduct of a long chain of mutations and selection. What we get is a purified version of the first cells. Still plenty of useless stuff in most DNA strands that is vestigial from a long time ago.
You must be a christian. Only christians make comments like this...
There’s a great animation showing this molecular machinery in action to scale and in real time. Look up a ted talk called drew berry animation of unseeable biology. Mind blowing stuff!
This is a telomere or ending sequence for coded DNA strands and tell the repair parts of the Cell not to fix beyond this point. Specifically this is a telomerase coding.
The videos had audio problem
There is a gap and pitch problem

First tell me one thing... This channel has around 48 lakhs subscribers but why views are only about 77k... I mean these videos are so cool nd well thought of... Why no one watches it....😕
one question, how long does the process of reading dna to a ready made protein take?
from my understanding in how computers execute a code, the process is pretty much instantaneous
Replicating and making pre m-RNA showed in the video takes matter of seconds for reading 50 to 70 neuceotides.
Next process (splicing) may take a few minutes
Next process (translation) may take seconds for reading 50 anticodons.
So it would take depending on the size few minutes
"you are not a delicious dessert sadly" 1:06
"What are you?"
"An idiot sandwich"
The ribosome is made of what material?
Wow, that was very clear and informative, thank you! I have a question. Do cells have a mechanism of restoring RNA if it’s damaged (by a virus, for example)? Like, can it detect that RNA is not a true copy of DNA anymore and re-make it?
No. However, the DNA has enzymes ready to check whether there is any errors in the DNA sequence. Like when there GT instead of GC.
@@jaykomp9597 and what does the check lead to?
@@22f94 The check leads to cutting of the RNA to prevent it from being transcribed to proteins which conducts all the actions we see. For further reading, such mechanisms can be seen in Si-RNA and micro RNA for regulating what is made in you. The field is called epigenetics
did you make the A T C G brownian motions on purpose ?
Considering the "electric Theory" and the "Solar Particle Forcing" Mechanism of course.
Oh telomeres! Niiiice!
Telomeres! Or the overhang at the end of it!
I had to look it up, but 5' TTAGGG 3' is the code for telomeres, which are present at the ends of each chromatid.
Who loves his DNA?
I love my quarks and beyond
Racists.
or, you know, everyone else who isn't self loathing.
Is it known where exactly in the DNA the information about what organs we have and where they need to be is?
"Mitochondria is power house of the cell."
5'ttaggg3' is for telomeres it seems or telomerease
Des informations intéressantes.
Oui 🌚
Damn Oliver Queen sure knows his biology.
Hi
I really appreciate your work
I have a question
If the all cells in any creature have the same sequence of DNA
What make the cell unique and differentiate
What makes that cell a skin cell and the other one is gland cell
And thank you very much
All cells in the human body have the same chromosome as you have stated.
A skin cell will activate a certain part of the chromosome for replication and make the helicase and RNA polymerase to bind and conduct transcription.
When I say activate, this is what I mean:
There are promotor codons and control codons before the gene. These condons needs certain situations for it to make the gene be promoted to get replicated and inhibited to prevent it to be replicated. These "certain situation" are controlled by the cell and its environment. So here, we can stimulate certain factors for a stem cell to grow as a skin cell by promoting certain genes and inhibiting others.
My eyes change between blue green and grey, please explain?
@Seeker 5:01 5'TTAGGG3' is vertebrate telomere sequence. Repeated thousands of times at the ends of human chromosomes. Where is my treat?
What do you can an indecisive organelle? A Mightochondria.
How those instructions exist? How those seemingly similar DNA and protein able to differentiate on what cells they're going to be? And going to the right place like where cells that made eyes supposed to be?
This is a simplified video sadly 😪
TTAGGG are the nitrogen bases, thymine adenine and guanine. The replicate as AATCCC and transcribe as UUAGGG :)
The very fact that some of the deadliest diseases thrive in our bodies tell us that our bodies are capable of playing host to them,instead of throwing them out or stopping them from growth.
you should try my first, to say that "I'm not a delicious dessert" >.-
We need a written copy of our DNA when we are young, so we can overwrite our older and corrupted DNA with our younger DNA.
If a always pairs with t and g with c how does an embryo get two different sequences from the sperm and egg? Wouldn't they just be the same?
The sequence of T,C,G and A in the father and mother chromosome could be different (of course if both parents had black eyes then they would have the same alleles (same sequence) if this gene only coded for the eye colour)
Wow I felt like a Genius there for like 30 seconds. Haha.
My eyes 👀 change colour all the time from brown to green, and when I was a kid I had tons of freckles across my nose and under my eyes, but as I got into double digits in age they started to dissappear, just some of the weird things that can happen to more people than you think 🤔
This would have helped me pass biology class
"Those beautiful brown eyes of yours" I must be colour blind, because I thought they were blue.
When you heart a comment, the outline disappears...
Wait, this isn't Tik Tok....
Can dna can be changed based on the food we eat
Where did the ribosomes come from?
But how Ribosome reads RNA? What is the mechanic behind this?
Probably chemical?
still cloudy as much as we know about dna they are many questions and missing links
This could be a class at school, easy
TTAGGG is the end of the chromosome called telomere. It shorthens after every cell division i.e. one cause of aging...
How does a cell know which part of the DNA is useful for itself?
biology is neat :O
It sucks many youtubers undervalue memorizing lines in videos. I guess it’s to do with closeups and budgets, possibly time considerations as well. But I get so distracted by watching people’s eyes jump around reading teleprompters that I can’t watch. My ADD starts firing. Pulls me right out. So I listen, but then I miss some of the other useful content.

MAKES A PERFECT HUMAN😂🤣😂🤣😂
TTAGGG is the base sequence of telomeres, the so-called caps at the end of chromosomes. Telomeres are shorten everytime the DNA is duplicated, dictating the life span of a cell. Certain carcer have the ability to restore telomeres, kick starting cell duplication, an advantage for the cancerous cell. At the same time, scientist are studying how restore telomeres as anti-aging strategy.
What a great time for science!
I owe my D&A to my DNA.
