DNA Replication Animation - Super EASY

DNA replication is the process of creating two identical copies from one original DNA molecule. DNA is composed of two strands and each strand of the original DNA molecule serves as template for the production of the complementary strand. Cellular proofreading and error-checking mechanisms ensure near perfect DNA replication. In a cell, DNA replication begins at specific locations, or origins of replication, in the genome. Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bidirectional from the origin. A number of proteins are associated with the replication fork which helps in terms of the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new DNA by adding complementary nucleotides to the template strand.

Animations help make molecular biology so much easier to learn. When I learned this as an undergrad it was so hard to remember it all! And reading it in books overwhelms you and makes it seem so much harder than it is. I love this video; I needed a refresher.

 what is this music....Feels like im gona get kidnapped by aliens

[TheWhiteGrin]

Watching this video mad me so disturbed and uncomfortable that i feel like my worst childhood nightmares all came together into one video

[SuperNumber]

Woah. The insides of cells have some intense acoustics going on.

I finally understood the point with Okazaki fragments, thanks!

[glossiegworl]

This is so much easier to comprehend than a professor talking about it with pictures. Thank you!

[jenna]

9 years later, it is still helpful to this day! Amazing videos like these making learning biology so much easier. Thank you!!

I can't believe how i spend hours on textbooks unable to understand this and 1 time of watching it finally made it clear.Kinda makes me angry at the stupid textbooks...

[kahoruishikawa]

My class spent like 4 weeks on this topic and I only had to watch it 5 times to get it <3. Life saver.

The Histones scared the shit out of me.

[LaughableXD]

Those DNAs look like they're having a seizure

[ChibiRyo]

So someone respond to this to see if I understand this correctly:
1. DNA gets unwinded by Helicase while at the same time gets treated by topoisomerase to keep the DNAs from breaking by the untwisting and twisting pressure, while Single-Stranded DNA keeps the strands in place
2.The leading strand gets coded by DNA polymerase smoothly at the 5' end to 3' end
3. The lagging strand, cuz it's technically facing the 3' end to 5' end, needs RNA primase to attach some Primers that attach some Okazaki fragments for template DNA, where DNA polymerase will eventually come and replace those RNA codons with the proper DNA codons.
4. Ligase binds and attaches any loose fragments together. 

Did i miss anything?

That is great stuff!  Easy to understand and high quality.  I wish this type of video and instruction had been available years ago when I was in school!

Thank you for the teaching of the DNA replication in the E. coli cell.

God bless.

[lilcharliefication]

the histone part was had a demonic feeling to it...especially with the audio, hahaha.

[lightning]

Am I the only one who finds this creepy?

[aves]

Beautiful. I really don't understan what is disturbing in this video?? It is just amazing animation of DNA-replication. A brief outline.

I love the wind instrument and how it keeps repeating over and over and now the noodles ride down and up the rollercoaster.

[sanashariff]

I have watched so many videos on DNA replication, and although this video looks like its been made in the 90s it has made the most sense to me! Thank you so much Medical Institution! Godbless <3
