Every time I have to remember which pairs go together, I just remember the round letters go together (C and G) and the pointy letters go together (A and T).

I have been watching Dr. Sammy religiously lately to remind my self of basic concepts I need for my exams. Your a life saver man

I have a cellular bio test tomorrow and was still confused on DNA replication, but you guys came in clutch!!!!

I often say DNA is like an expensive cookbook in the reference section of a library (the nucleus) and mRNA is like a photocopy you make of the pages you need. This analogy would have been much more relevant 20-30 years ago!

I literally just finished making an EdPuzzle for the older Crash Course on this topic!

So now we see why Wolverine developed bone claws and a healing factor.

So well explained. Thanks Sammy and the whole team

Extremely well done and concise!

Thank you so much! This video is exceptional. It's as entertaining as a movie and as educative as it needs to be.

Such an interesting report, thank you

That’s a lot to digest but I love it!

Wow a lot of this I haven't read about in over a decade! This is only the second video I've watched so far but awesome videos!

Its always feels amazing to be the first in a Chanel that you really like 😂❤

Another piece of knowledge installed 🎉🎉🎉

Do you have videos on good stress vs. bad stress, resilience, and all forms of mental health promotion and prevention?

Another great video.

Lol just im learning English and now I step by step understanding that I need to learn a lot and a lot by your videos

All the best buddy!

I just graduated from high school a few months ago and I still watch this sometimes and the funny thing is science was one of my least favorite subjects 😄

Great vid

Awesome 👍

The music of Crash Course - is the same as the ringtone Seedling in iPhones, right? Are these based on any important western musical compositions? Thanks!

Thank you

Oh I love this topic!

I think at 3:30 we can also make another mnemonic like remember it as G3 Cat2 (or just G Cat), G has 3 bonds with C and A has 2 bonds with T. Hope it helps.

6:15 yes dr. Sammy, you are!!!

Wonderful

Do you guys purposely use angel numbers to time your youtube video timings like 13:31, 13:13, 12:36, 12:34 and 11:11. Coincidence, marketing tactic or purposefully done for motivation? Love the videos!!

Thank you!

Hank: you wanna make one?

Wonderful 😊 I hope that there is an Arabic translation ❤

human genome was decoded in '01

The human genome project was declared complete in 2001 but it only contained 92% of the genome (at high accuracy). It took until 2022 to fully complete it, IIUC mostly because a lot of the gaps had a bunch of near-identical repetitions of sequences, which made it hard to confirm exactly what was there with the fastest techniques we had for reading DNA.

A large portion of it was, arguably the most relevant parts to medicine (protein coding genes etc) but the full end-to-end sequence of each chromosome was completed in ‘22. Mostly. I’m sure there are still bits that are missing, for a variety of reasons.

It IS incredible that life can work with a four letter alphabet, from two different angles - one being "only four." The other being "FOUR?!" Because us humans created the entire Internet out of ones and zeroes. Binary can certainly function for lots of complex stuff! So having twice as many pairs to work with? It's double binary! (I recognize that I am no doubt vastly oversimplifying here.)

BIOCHEMISTRY CRASH COURSE WHEN?

*Teleological language for science is a bad choice.* To declare (as in the video title) "Our Instruction Manual for Existing" raises the question: _Who is the Instructor?_ And then there are the ancillary questions such as what if one does not want to follow the instructions?

Guys, here me out! Dinosaurs 🦕

So all of this is by excidant

"Most useful?" Wouldn't the "most useful" instruction manual be something that most humans could _actually use?_ In all of human history only a handful of humans have been able to do that so far.
