DNA Replication: Copying the Molecule of Life

Your DNA needs to be in every cell in your body, so what happens when cells divide? How does each new cell retain all of the genetic information? The DNA is able to copy itself through a process called replication. Let's go through the finer points, shall we?

Gotta love how with quarantined schooling teachers have given up on teaching and recognized that people like you have been the ones actually teaching us.

You literally just summarized about half of what I learned in an entire semester-long molecular biology class in a 6 minute video. Nice.

Even with a biology degree and in medical school, this is the most straight forward and easy to understand video on DNA replication. You sir are the GOAT.

You single handedly made me not only pass but EXCEL in my biology 101 class. Thank you professor dave

I just realized something very important in terms of how to interpret your animation.
The directionality of the synthesis of the new strand is correct. However, I initially thought that the numbers you put on the leading strand was identifying the ends of the new strand, not the original strand.
In other words, the new strand would read/synthesize as such: 3' under the 5' of the leading strand and 5' under the 3' of the leading strand with the arrow going in the same direction.

Every time I struggle to understand a course material and find out you have a video for it, I cry tears of joy

Thank you Prof. Dave! I spent like two hours trying to understand my professors lecture, and you helped quite a lot! I am really grateful that I found this video online. Thank you for what you do! :)

[adamgurman]

A great, fast, easy and organized video! Thanks!

[myvideosfortheworld]

sir you are a really talented teacher and a speaker a process which would take me hrs to understand was made easy by you and i got it in juat 6 mins ! thanks man

[kellyedsall]

This helped me so so much! Your video really cleared this up! Thank you!

I enjoy that I can learn the basics from your mini-lectures. Great job, Professor Dave. You put me in mind of my late father, a physician, teaching me about reproduction, mitosis, meiosis, etc. He started with onions and went on from there, ending with human reproduction when he felt it was age-appropriate (about 13-14 in my case). This puts me in mind of his teaching methods.

I just subscribed a couple of hours ago and will be adding your videos to my Geology/Volcanology and Evolution and Extinctions playlists. So glad I found your channel!

[yashgokhale]

Super helpful! Would have taken hours for me to understand just by reading this.
Thank you Sir!

[sierraschopp]

This is such a great video! short and sweet :)

[mushfiqurrahmanshishir]

Thanks for this explanation. Some things are simplified. But this is a very good overview. It was really helpful.

[moffeevalverde]

I love the way you explain each step of DNA replication and other biological processes in your videos, I'm just glad to find your channel :')

You are awesome.. I was jumping from video to another and I can’t understand that. But with you just in 6 min I take it very well !!

[chloeli]

5' and 3' DNA template strand should be more specific indicated in the slide. Its a little bit confusing.

[zaraanwari]

Video was crystal clear . I understood the whole topic In ONLY 6 minutes where I didn’t get one thing through my head in a 80 minute class . Thank you so much Professor Dave !!

[atiyadavids]

Best explanation I've ever heard and seen my whole life. Ily.

[mayamade]

This is one of the best videos I have seen on DNA Replication!! thanks a whole whole lot!!
