Biotechnology: Crash Course History of Science #40

The history of discovering what DNA is, what it looks like, and how it works is... complicated. But, in this episode of History of Science, Hank Green does his best to lay out the basics so we can understand the beginnings of Biotechnology.

It's cruelly ironic that Franklin died because of an error in replicating the structure of her DNA.

"Watson was a psuedo-scientist and stupid" this was the phrase of my teacher who said it at the starting of the lecture when she was teaching genetics. 😂😂

It makes you wonder how many scientific discoveries had women who were central to the progress, but got written out of history...

It's almost 4 am. I'm in a lab, imaging gentically modified worms (C. briggsae) ie using watching this.

Im going to school for Biotech this month, wish me luck. This video was awesome and gave me an intro to what ill be doing, Im very excited now!

[Rafma]

I’m taking intro to Biotech for the summer 😅

Yes!!! I studied this and we did a lot of sequencing! Tough class but very interesting

8:57 not entirely true. moleculat phylogenetics has truly been a revolution in the study of evolution. however, physical features are still used to study evolution. in fact, it is the only way to study evolution in fossiles, like dinosaurs. dna in evolution can only be used in non-extinct organisms. and physical features are as much reliable as dna, since molecular phylogenetics have many issues and problems as well. in fact, you can get many different results depending on the dna sequence you use, or the algorithm to build the phylogentic tree, or to build the multiple sequence alignment. same basic problems with physical features.

Can you please make a video on HUMAN GENOME PROJECT???😍😍

Shrodin-JER?! With the trend of the unusual pronunciation of names in this series, I feel like you are trolling us :D

[AlexRace]

Love this channel! I’m inspired to make more videos to help high schoolers !!! 😝😝

[jeremiasrobinson]

This is a great series and I hope to see more like it.

The matching plaids on Hank's shirt make me so happy

0:15, don't u mean, what is love?

10:32 by the way, that is where Michael Crichton got the idea for his novel Jurassic Park.

Life is a cocktail of pain, disappointment and boredom.

[rutythegames]

If you have crash course games why don’t you try crash course anime. You could teach people the oldest anime ever and how anime evolved to how popular it is today

I can excel at anything if I take it very seriously.

3:26 in fairness to Watson he is also so astonishingly racist that almost no one is still willing to publicly associate with him.

[SmajdalfFrogi]

The pronunciation of Schrödinger is killing me... Other than that great video :)
