Mitali Patil says:

t-RNA thou art a heartless bitch

Mo Hamza says:

go to 11:37 the titin's constituents start to overlap, I'm really focussed as you can see!

Jaime Vazquez says:

Great refresher for those currently taking biochem!

mimi goddest says:

who else has a final tomorrow and didn't study?

Bri Landy says:

I'm glad I now know that my wrinkled sheets are caused by promiscuous amino acids.

shann salih says:

pause at 13:42

mira hanafi says:

Thanks to all CrashCourse members for making these videos a huge success! i love all your videos and they are actually really helpful. God bless you and have a great life ! :'D

Valentin Hämäläinen says:

Did anyone else pause to see when the name was scrolling on the bottom?

rosegirlkrb says:

i want a hot pocket now

Pnuema Morosa says:

titin ends in leucine

LY Spray Art says:

I can make the word go in whatever direction I want it to go, if I want it to go right, it goes right and vice versa. Try it and amaze yourself.

Laken Gross says:

So my biology teacher calls you my boyfriend… yea! But I love these videos…

Cole Dupuy says:

Wow, great video. Only like ten percent of it stuck, possibly less but it's still a good video.

TheUkiahAdventure says:

I would love to put my ham in your hot pocket any day……. sorry couldn't resist!

Mahogany Joiner says:

Great Information! it was hard to keep up though and I had to keep going back because of how fast you're talking lmbo
