6 Steps of DNA Replication

[@sujufan009]

This is by far the best DNA Replication video I've watched, thank you very much.

[@petersiska7510]

Emphasizing reading from 3 to 5 and writing from 5 to 3 is not effective the explanation is too stretched it could be effectively explained in half of the time

[@andreainzaghi7373]

I agree it is the best becaue it explains WHY and not only WHAT and all of that in ten minutes

[@Lisa.pizzza]

This is the honestly the only video on DNA Replication that made sense.. you've pretty much included all the important parts without being too fancy.. simple is better!

I just found out that Dave Carlson is battling a brain tumour. I am currently studying for the MCAT and the videos from PremedHQ have been very helpful. Dave is a wonderful instructor. I will be donating to his gofundme as a sign of my utmost appreciation.

I believe what makes a good teacher is ability to tell your students what they don't know and all they need to know about that, not telling them what YOU know!

Thank you Sir. I am not a natural English speaker, that's why I really enjoy your eloquence, the varity of your choice of words. Now all my questions concerning the issue has been answered.

[@opeemboya8042]

I love it too. The tutorial is much easier to understand. English is simple with no deep accent. God bless you sir.

This man taught me what 7 HOURS of lectures from an ego inflatted professor couldn't fluidly communicate!😂😅😢🎉

[@courtneymorris1985]

I was really confused after my professor went over this in class, but after watching this video it really gave me a better understanding of how DNA replication works!!!! THANK YOU SO MUCH!

That's great to hear! If you think your classmates may find it useful, please do share this video with them! :)

@@PremedHQ professor how do dna polymerase know what exact new dna to produce do they get their information from the coding?

[@bakarolachika187]

@@mmd123king6DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones.

[@mmd123king6]

@@bakarolachika187 I do know that... what im saying is do they do this once? and then they dont have to read it again becouse dna gets saved up onto the system or they have to do it before every replication time? That was my question

[@Modiferify]

Omg he explained it very well!!!! I Have been looking for a good explanation and I swear i was postponing the exam of molecular genetics a lot .Because the Professor asks the mechanism of Dna replication! I'm so glad i found this explanation. I know nobody is stupid but we sometimes need someone to clarify our ideas and help us understand more. THANK YOU A LOT.

after personal trainer, I took up sport science university and this is the ONLY VIDEO (or almost only) that explains the reason why Okazaki fragments occour!! not only DESCRIBE but also EXPLAIN (the story of the new primers) very well done

[@romangurung3825]

Heartily thank you sir. I had come here because i did not able to take clear concept of my lecture and mam was asked questions but i was not able to answering to mam. However mam challenged me next lecture. Through this video i will explain more than mam could expect from me.

[@mandalorian4620]

Minor correction: First: A-proteins separates the strands initially at AT-rich areas throughout the strand (so replication starts at multiple places simultaneously). (Not a critique, but you forgot them). Second step: SSBs keep the strands from annealing, like you said, while simultaneously helicase unwinds the DNA to further separate the strands. After that Topoisomerase is also important, since it reduce the tension, caused by helicase and thereby prevents supercoiling.

[@jamiek6471]

Hello! I was trying to find some info on A-proteins but could't find any, can you please share a link where it's written about them? i would appreciate it, thank you!

[@melissaatanga4337]

whats AT pls?

[@ahmadfadda2654]

The origin of replication depends on whether the cell is eukaryotic or prokaryotic. In Prokaryotes, the DNA is circular and there is only one origin of replication. What you refer to as A-proteins are the initiator proteins that bind to the origin of replication. In E.coli, the initiator proteins are called DnaA & DnaB. In eukaryotic cells,there are multiple origins of replication on the linear DNA molecule. The initiator protein in eukaryotes is called the origin recognition complex.

[@brendawilliams8062]

I’m not sure but it appears they have a leading and lagging computer complexity. I see why the computer fans are getting excited over. Not that it’s resolved. Yet it’s clearly the complexity.

[@shirokuro73]

I'm a complete layperson, I have no medical education or training whatsoever. I understood this video, at least at the logical level of what each enzyme does, etc. Thank you for a great video!! I started watching videos about SARS-Cov-2 in an attempt to understand more about it, and now I've fallen down a rabbit hole and I think I want to learn a lot more about molecular biology now. I want to learn way, way more about the processes involving DNA, RNA, cells in general - but more than that I'd love to understand how, physically these things work. Ultimately all of this boils down to chemical reactions, right? That's what I'd love to understand. Molecule X bonds with molecule Y due to its shape, structure etc, and BOOM - now you have what's essentially code being executed and - life. Maybe it's my computing science background which is causing me to be so fascinated by this world which until a week or two ago, I knew zilch about (and still do compared to someone who's actually studied it, of course). My mind is kind of blown and I can see me continuing to fall down this rabbit hole. Maybe I'll start looking for actual constructed courses, but for now, videos like this are a great place to start. Thanks again for such a clear, well structured and explained video!

[@akka77]

omg you are literally a GOD of biology classes, thank you so much!

[@saraikwizera6907]

My online teachers never ever explain things like they never told me that replication always starts at 3' and moves towards 5' which is one of the things that confused me so much. They never really explained what a primer was they just told us that it starts the process of replication. Like what?!!!! Teachers like you have made my life so much less complicated

[@lucky41210grl]

Clear, concise, and makes perfect sense. I love that you explained popular words that we commonly hear when discussing DNA replication, but may not have fully understood well. We have all heard the term leading strand, lagging strand, semi conservative, etc. but explaining exactly what they mean in conjunction with the full video explanation really increased my understanding.This attention to detail and your clear understanding of the topic really this video apart from all others.

I think I'm going to cry ,thank you so much for this..

[@ajangu60]

I am Soo grateful for this! Been thinking a lot about this topic and always encountered problems when studing the lagging strand. Thank You for explaining it soo simply and understandably! The enzyme reads the strand from 3' to 5' but the new one is made from 5' to 3' carbon + since the helicase continues to open up the DNA and the ''lagging'' strand is making DNA in the other direction, it simply needs new primers from time to time to catch up with the replicaton fork!
