There's another amazing video regarding steps of DNA replication. You must check it once. I hope this might clear all your doubts. Links here. th-cam.com/video/oa6gjPZS2kk/w-d-xo.html
In this video , idk if i didn't understand replication or not , but the enzyme at 2:41 is not supposed to be able to move that way( to take that direction), it is supposed to be linked with the second DNA polymerase and take same direction. Sry for my english hard for me to explain hard lessons with a language i don't master.
I'd lost all the hope that I'd ever understand replication, after watching this precise , short and easy-understanding video , I'm feeling refreshing now. Hats off to that person who made this...
@@anonykitsune ikr this topic is really hard if we just try to read it- It requires high imagination power to actually visualise the whole process. Anyways don't worry too much and just think how beautiful the whole mechanism is. And all the best
@@anonykitsune i get questions like that too, but i think it’s just to test your critical thinking of the particular subject. the questions contain info that i’ve studied, but it is worded in such a way that makes me confused af lol.
This video is amazingly incredible. It is precise, up to the point and explains everything in 3:28 min with clear voice with synchronized animation. This video is the best that explains Dna replication on TH-cam. It probably deserves a million likes
Step 1: Helicase Function: Helicase is the initial enzyme in DNA replication. Its primary function is to unwind the DNA double helix. It accomplishes this by breaking the hydrogen bonds between the complementary base pairs, such as A-T and G-C. By doing so, helicase separates the two DNA strands, creating what is called a "replication fork." This single-stranded DNA region is where the actual replication process will take place. Step 2: Primase Function: Primase follows helicase. Its role is to synthesize RNA primers. Primase adds short RNA sequences, known as primers, to the DNA template strands. These primers are essential because DNA Polymerase, the enzyme responsible for adding new DNA nucleotides during replication, can only extend an existing strand. On the leading strand, primase synthesizes a single RNA primer at the 5' end, providing a starting point for DNA Polymerase. Step 3: DNA Polymerase III Function: DNA Polymerase III is the primary enzyme responsible for DNA synthesis during replication. It adds nucleotides to the growing DNA strand. On the leading strand, DNA Polymerase III synthesizesthe new DNA strand in a continuous manner by extending from the 5' to 3' direction, using the parental DNA strand as a template. This strand doesn't encounter the same challenges as the lagging strand, which requires a more intricate process. Step 4: Exonuclease Function: Exonucleases come into play after DNA Polymerase III. Their function is to remove RNA primers from the DNA template. Once the RNA primers are synthesized by primase, exonucleases degrade them, creating gaps in the DNA strands. On the lagging strand, multiple RNA primers are synthesized at different points along the template to provide starting points for DNA Polymerase. Step 5: DNA Polymerase I Function: DNA Polymerase I is an enzyme responsible for gap-filling. After the removal of RNA primers by exonucleases, DNA Polymerase I replaces the RNA nucleotides with DNA nucleotides. On the lagging strand, DNA Polymerase I works in a discontinuous manner, filling in the gaps created by the removal of RNA primers and synthesizing short DNA fragments called Okazaki fragments. Step 6: Ligase Function: Ligase is the final enzyme involved in DNA replication. Its function is to seal the nicks or gaps in the DNA backbone. It does so by catalyzing the formation of phosphodiester bonds between adjacent nucleotides. On the lagging strand, ligase joins the Okazaki fragments together, ensuring the integrity and continuity of the newly synthesized DNA strand. In conclusion, DNA replication involves two strands: the leading strand, which is synthesized continuously, and the lagging strand, which is synthesized discontinuously in Okazaki fragments. Different enzymes work together to ensure the accurate replication of both strands, preserving genetic information during cell division and ensuring the inheritance of genetic traits.
Your explanation is very useful it clear all my concept i take screenshot of your comment so I can recall my concept whenever I want and I wish this explanation was written in my book so I could cram it ❤❤
Life isn't perfect. Otherwise why does DNA polimerase make so many mistakes and some lead to detrimental mutations? Why do cells suddenly abnormally proliferate and create tumours? I'll tell you what. Life isn't perfect. It's _good enough_ . Good enough that it can survive and thrive, but never perfect. Contemplating upon life itself and its mechanisms does not warrant the immediate conclusion of "this is no accident" or "someone _must_ be behind this". I suggest you step out of your initial reaction which may be corrupted and actually think critically for a second.
TrEs 2b the fact that DNA can correct itself is fascinating. The fact that something this small yet so complicated can happen in every cell is fascinating. It is logical and scientific to look for the source of something (existence). Just because you have an opinion, doesn’t mean theirs is corrupted and not critical. Life is perfect because of its imperfections. Idk what I’m trying to say exactly, but don’t force ur opinion on others :)
Easily the best replication video I've seen to date, thank you. I don't understand why it's so difficult for professors to explain this in a simple step by step process. I get that it's a complex topic, but damn, just go step by step. Stop talking about random enzymes in no discernible order.
DNA REPLICATION (semi-conservative bc each DNA molecule is made up of one old, conserved strand of DNA): 1 - separation of 2 strands (unzipping done by helicase, result: replication fork) 2 - separated strands provide template to create new strand of DNA (started by primase, which creates a piece of RNA called primer --- this is the starting point of the new strand of DNA) 3 - DNA polymerase binds to the primer and adds bases from 5' to 3' (in the leading strand). on the other hand in the lagging strand, DNA polymerase adds bases in a series of small chunks called the okazaki fragments 4 - once the DNA has been made, exonuclease removes all RNA primers from both strands of DNA 5 - another DNA polymerase fills the gaps that are left behind with DNA 6 - DNA ligase seals up the fragments of DNA in both strands to form a continuous double strand
I learnt DNA replication from ritu man seriously telling mam ki lecture ki baad animation ki jarurat nhi hote h pr m ne yeh dekha or bhi clear ho gaya❤️🔥why not school teacher teach like this ??? Fir bol te h bache nhi pdh te
I don't understand why teachers can't explain like this ; slow and straight to the point . All they do is draw a diagram ( totally not realistic ) and ask us to write notes . And we are like lol what just happened .
Not everyone has a gift to be a teacher...for being a good teacher you have to have empathy so you are able to imagine yourself walking in shoes of another person, therefore, you are able to explain things extremely well as you are imagining how they will perceive the given information.
My teacher explained wayyy too many details which made us all confused . Single strand binding protein , increasing efficiency of dntp addition ,etc. All gone over the head
I'm in my senior year of high school. I'm learning protein synthesis and DNA replication. I really like this animation, it's great to have universal scientific facts even in a different language! My teacher's voice echoes in my mind
Best video ever to show DNA replication! No other video that I could find really explains in a short but well detailed manner. Other videos I feel are for those who are already familiar with the process. This is my first year learning this process and I'm grateful I found this video!!
Look at the bright side: at least he has self-critique. I'm re-learning biology over a decade after leaving high school, cause I was always interested in it, it's just all my teachers were... Bad. lol
This was very helpful, I've been studying this for a few days now but I've always had a fuzzy picture of how the lagging strand is formed. Your video cleared everything up. Thank you!

Here is a basic, simplified version of the video: Adenine --> Thymine (in RNA it would be Uracil) Cytosine --> Guanine -The Helicase splits the DNA, for replication -Primase adds RNA bases (primer) to top strand, known as the leading strand -DNA polymerase binds the primer to the DNA -This goes 5' to 3' -For the bottom strand (lagging) it adds RNA bases in fragments (Okazaki segments) because it goes 5' to 3' -Exonuclease removes some RNA primers -DNA polymerase then adds DNA to the missing spots. -Ligase makes sure all the fragments are sealed -DNA is described as semi-conservative, because there is one old and one new strand of DNA in each DNA. Thanks and hopefully this will help you for your bio test I know it did for me :)

Any medical students here in 2024😊😂
Thank you so much . I'm a A/l biology student in sri lanka 🇱🇰
This video is very helpful to me 🙏
정말정말정말 감사합니다
Thank you sooo much 자막 달아주신분두요ㅜㅜ
Wow you are a life safer. Thank you so much. This animation should be shown in every biology class on this topic.
Edit: I suggested it to my teacher. It might have an impact. Good job!!!
Anyone here just because they were curious and are not studying any related majors?) I read about genes from a book but it was only information dump, so grateful to whomever made this animation, very useful 🙏
The old but gold DNA replication 😁 This is so inspirational. Thank you so much, It helps a lot in learning, but also revising.
Isn't this enough to give us a thought about why r we created so perfectly ?
Hamare geetendra sir bohot achha padhate hai 👍🏻 Aur bohot sare animations bhi dikhate hai..mein sirf revision ke liye phir animations dekhati huu.
My life I must be a visual learner this is the first time i have ever had a clue about the lagging strand
Out of all the DNA replication videos this one is so good, very detailed and easy to understand thank you
thank you for doing this - from a Vietnamese student at high school.
Any neet student here😅

Yehh 😂

I love how the first strand replication process is very simple, while the second strand replication is 100x more complicated lol.
As a senior bio major I shed a tear watching this... so beautiful so beautiful so beautiful so beautiful
can't believe i haven't found this earlier after so much of my time wasted trying to look for a simple explanation like this. thank you so much i finally understand it.
Here is a basic, simplified version of the video:
Adenine --> Thymine (in RNA it would be Uracil)
Cytosine --> Guanine
-The Helicase splits the DNA, for replication
-Primase adds RNA bases (primer) to top strand, known as the leading strand
-DNA polymerase binds the primer to the DNA
-This goes 5' to 3'
-For the bottom strand (lagging) it adds RNA bases in fragments (Okazaki segments) because it goes 5' to 3'
-Exonuclease removes some RNA primers
-DNA polymerase then adds DNA to the missing spots.
-Ligase makes sure all the fragments are sealed
-DNA is described as semi-conservative, because there is one old and one new strand of DNA in each DNA.
Thanks and hopefully this will help you for your bio test
I know it did for me :)
Student from Iraq
There are two days left until the ministerial exam for biology , I'm here reviewing the subject
This is one of the best videos for explaining DNA replication, thank you!
I learned more biology in this video than 10 lectures worth of biology i am amazed
Best and easy way to understand and better than protracted videos
I'm in 12 standard from INDIA 🇮🇳 & I found this video which really boosted my knowledge ☺
Hiii
Finally I'll be visualize the process of DNA replication
'The best things in life are available for free' this video totally proves it. Thank you so much
So much easier to understand when its visualized
Best animation ever,and the lady was explaining very good👏👏👏👏👏👏👏👏👏👏
Fantastic explanation...every time before my exams I use to watch this video for better clarity...
Very easy to understand whole process of DNA replication through this video...thanks a lot😊
I really hope all y'all who are watching this begin to think to yourselves, "How can this incredibly complicated process have risen by undirected, blind chance?" These perfectly-tuned enzyme mini machines do their respective tasks with unparalleled precision. Tell me, which evolved first, the enzymes or the DNA?
This 3-minute video explained the concept better than a 90 minute lecture by my professor.
hands down the best video explaining this concept, and trust me I looked at lots
Who's here after vipu bhaiya's class 😅?? Lakshya 1.0
what is lakshya 1.0
しっかり海外でも岡崎フラグメントになってるのなんか感動
🐴🐴
Anyone here because they're gonna turn spiderman with a new experimented dose of spider genome lol
Just u eren
Amazing❣!!! You have nailed it in minutes. I love how you explained everything about DNA replication. It was perfectly matched with an animation that adds to the total presentation. Your video is fun to watch and easy to understand👏👏
Watched this video when I was doing Odinary Level.
Here i am again watching this video at my 2nd year in medical school 6 years later.
Thank You
Wow, what an amazing video! Incredible animation of this complicated process...helped me a lot with my schoolwork.
One of the most helpful video I've ever seen. Thanks for it.
Tarun sir explained it very nicely even without 3d
Now after seeing 3d i feel as if I am revising his notes only.
Thank you Tarun sir🎉
If I have these videos on every topic, I'd be the smartest student in my university.
god bless the maker of this video.Finally I have understood the process of DNA replication. Its really Owsome!
owsome realy
just imagine how many hours, days,months were spent just to make this small video. hats off to the maker.🙏🙏
This is seriously the best video on TH-cam about this topic 🌝❤
