Watch part 2 here : • Dna Replication Part 2
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
In a cell, DNA replication begins at specific locations, or origins of replication, in the genome.[3] Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.
DNA replication, like all biological polymerization processes, proceeds in three enzymatically catalyzed and coordinated steps: initiation, elongation and termination.
Replication fork
Many enzymes are involved in the DNA replication fork.
The replication fork is a structure that forms within the nucleus during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together. The resulting structure has two branching "prongs", each one made up of a single strand of DNA. These two strands serve as the template for the leading and lagging strands, which will be created as DNA polymerase matches complementary nucleotides to the templates; the templates may be properly referred to as the leading strand template and the lagging strand template.

How can someone voice is too soothing 🤍
Im going to share this with all the doctors I know, because I have never found something as simple and excellent like this! thank you! greetings from a Latin country! :)
Thanks bro

I thought you were dead Alaska🙂
Yes brother this is very helpful video for us
Bless you, none of my reading would tell me what "5 prime" or "3 prime" meant and this is so so helpful! Your drawings are so satisfying to watch, and so clear. Thank you!
Thanks for explaining about the 3‘ to 5‘ concept in detail, I haven’t seen that in other videos and it helps me to relate this to other concepts.
Awesome explanation... Just last week my friend suggested me this TH-cam channel and I have viewed this video many times... Good for revising
Great explanation and animation.
Your voice is very calming.
Keep it up and thank you so much for helping me understand such difficult topic so easily.
Waiting for new videos.
+simrah begum thank u so much for the support begum. Really appreciate it
Nicely explained the process. Best part is the point to point explanation given with basics along with the soothing voice 😊. I wish we would have access to such things during our college time.
Full detailed and easiest explanation of DNA Replication ...👇🏻👇🏻

@@MEDSimplified if a dna gets disapers does the body know what was missing using the codones and produce it again? Im a student and i have a exam comming up pls help sir
Love your teaching dude. you just made everything simpler.
My teacher made us watch this so I didn't want to but now that I finished I'm glad I did. The animations really helped me understand what the heck is going on
A very helpful video - thankyou so much for taking the time to produce it.
The best explanation ever I hv seen about DNA replication
Absolutely loved the explanation. You have a flair for explaining things well. 👍
many thanks, slides and animation-outstanding, explanation-outstanding, voice -very calming and enjoyable to listen to. I was wondering if I can get text of your presentation.thank you once again
Please sir we need transcription and translation related lecture,
because our exam is near.
Could u please make a video on ATP formation, light and dark reactions of photosynthesis and ABO and Rh blood group systems... will be really thankful
thanks a lot !!! I just finished my STPM biology paper and one of the essay question is about dna replication. Thanks for easier explanation about this topic which lets me more unstanding about the process of dna replication😆
you have made such an OUTSTANDING VIDEO. Really thankful to your channel. I dont think any appraisal would be able to suffice your hard work & presentation.
Please make more videos on allllll other biology and as well as chemistry. Thank you ❤️❤️❤️❤️
It is the best video that I've seen on replication. I loved it. You are great. Keep it up 👌 and nice voice man.😄
Sir, thank you for helping us learn mol. Biology in a better and more easier way.😊 your videos are always so helpful.
Thanks for these videos. Really simple and easy to understand. Keep ‘em coming! :)
+Ghost Seeker thank you so much for your appreciation sir
Your video is great . your voice is so calming thank you so much and your teaching really helps me during my exams thank you
Mee expalination chala bagundhi v r getting interested to listen wht ur teaching.... thank you for gvng more videos...
You made it crystal clear thank you so much, Your explanation is good enough even I laughed when you asked for a 100 like , you have 280K subscriber now and you deserve it , keep going

Awesome.... Now I am learning the concept very clearly..
Excellent superb channel for students and also for teachers, thank you for this contribution.
I rarely comment or like videos but your pedagogy and content compels me to do it
2:30 A bonding with T and C bonding with G is called Watson-Crick base pairing, when human names are used. Chargaff's Rule was similar, but different: it only said that the amount of adenine is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine. It does not attempt to explain why, and doesn't involve base pairing. It is one piece of information that Watson and Crick used to come up with their model, which had A bonding with T and C bonding with G.
Brilliant explanation Sir you really made my day , I would love to give you thousand likes for such amazing explanation if it was possible ...Keep making such amazing helpful videos 😄😄👍💐💐🌹🌹
45 years after graduation, i recalled. DNA. very nicely explained.
Great video! Answered all my questions. Keep it up
wonderful
Excellent. Better than 3 other vdos I saw
No words to express,you are amazing is an small word to say you,, I got an full clarity thank you so much 🙏🙏🙏🙏🙏
Yup
In which class you are
Better and Cristal clear then any other video 👍
Hi your videos are very nice please make a video on regulation of gene expression and lac operon.
many you tube videos exist, but all confuse us more than elucidating. Thank you for clarity. May be we should also get some still pictures as the video goes on to refer to them in piece meal
Hey man... 1hr concept in just 9 min omg it's really great ... Full clarity ...
It is best and simple to learn and please keep the vedio by explaining the biology text
Your teaching directly fits in mind..
Sir, can you provide a video on linkage and recombination
Great great thank you for your explaining 😊
