Gel Electrophoresis

Special thanks for feedback from Dr. Brian W Davis and his team at Texas A&M University!

Major Points in Video:
Intro 00:00
(Example of) How Gel Electrophoresis Can Sort Molecules 1:42
Restriction Enzyme Role 3:20
Example 1: Mother and Baby Guppy Electrophoresis 4:31
Longer DNA Fragments vs. Smaller DNA Fragments 4:49
Example 2: Problem Solving with Gel Electrophoresis 5:33
DNA Ladder: 6:05
DNA Fingerprinting 7:14

CORRECTIONS:
1:39 we should add the word "tool" like we mention at end of video as gel electrophoresis is a tool used in the field of biotechnology

Clarification pin! 1. As we mention, guppies do *not* lay eggs. So in our video, we are trying to emphasize how cool it is that they have live birth! You won't find eggs in the aquarium! (Making them great for the beginner aquarium as many times extra care must be taken for ensuring egg survival in egg laying fish). But a good comment made us realize we need to clarify: we are talking about what you see in the aquarium; however, we want to point out female guppies still carry eggs internally within their bodies. Which is interesting as they develop internally so that the babies can be born live. Sorry, we wish we had expanded the video to include that fact of development within the female guppy. 2. At 1:39 we should add the word tool so that it says "and that biotechnology tool is gel electrophoresis" as it's a tool used in the field of biotechnology, which isn't stated till end of video.

i love having everything explained to me like i'm 10 years old while i'm at my last year in college

[DWTHAN]

As a 23 year old working in research and running those gels almost every other day, I have to say this is the best explanation of the science behind it that I have ever seen!

[noam]

There is a generation of physicians, biologist, dentists, nurses, bioengineers and many more, from all around the world, that will admit to schools of even finish their degree thanks to this masterpiece. Thank you so much!

[henrysheffield]

My science teacher uses your videos in class! Very well explained and made videos.

[Mockanters]

Lets be honest, this is where we all go to before a quiz or a test.

[studytee]

I loved this video! It was both informative and easy to understand. I'm super glad I've found your channel! ☺️

[juliariccobono]

I am graduating with a B.S. in biotechnology this week and this video is amazing! The whole channel has such great videos! If only I had discovered this channel my freshman year

[EH_]

Thank you so much. We've recently performed an electrophoresis lab, but our instructor never elaborated on why we were doing it or its importance. Again, thank you for clearing things up.

[elizabethrae]

Just wanna say I’m in grad school and I use your videos to help me understand things I don’t grasp in lecture. You’ll never completely know your full impact! Thank you for all your help!

[SC-keln]

I was completely lost and had no idea what gel electrophores is when my biol lab professor talked about it.... this video is just my life saver....

[kelseybogdan]

my FAVORITE science videos on the internet by far :) Such a joy to watch, and I use them all the time to help the kids I tutor. They are so well laid out, clear, and engaging !! amoeba sisters fan 4 life

[ariasijiali]

Studying for my IB Mock exams with your super comprehensive playlist! You really helped me hack my biology studying. I also laughed and "awww"ed SO MUCH in this video the people sitting next to me @ starbucks think im mildly demented. Thank you!

[karengao]

Loved this!!! The animation, the funny comments, the narration, the hypothetical situation to better visualize an abstract idea. This really helped me in my AP Bio class!! Thank you!

[coffeelee]

I already learnt this at school but still watched it just because of how cute and easy the video is

[sspanakis]

Mrs Suchoski always shows us these videos. I want to make my point very clear, she is the best biology teacher in the land.

[ZABABAK.]

Im a medical student and I can tell doctors back there in my university couldn't do what you'v just did
I love you guys ❤

[santiagoeckert]

My science teacher at Cartersville Middle School shows us your videos to learn about Eukaryotes and Cells and Ribosomes and we are just so engaged in what y'all have to say and Thank you

[ahmedboubaker]

I LOVE your Videos.I want to be a geneticist when i'm older and when you talk about genetics in your videos it really helps me so i cant thank you enough.THANK YOU AMOEBA SISTERS.

[Ycvike]

Who is better than the amoeba sisters?!!?! From elementary to college as a nursing major they always have been awesome.
