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!!!!

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 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!

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

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 😄

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.

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

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.)

*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?

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!!

human genome was decoded in '01

@DracarmenWinterspring 10 ай бұрын

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.

@chinobambino5252 10 ай бұрын

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.

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!

"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.
