I can't express how much this made sense at such a crucial time. Thanks a bunch.

[brookecarlson]

what the heck is wrong with the audio? It's repeating itself, and then sometimes disappearing..

[chandrashekharchauhan]

Just wow.... How do you guys at khan academy make such brilliant content?? Such complicated stuff explained with such clarity and made really simple, as if I was watching it happen, live in the lab.
Thanks and love from India

[danielmillan]

Don't listen what the people say thanks man you make amazing videos

[Misstigrine]

cDNA from the mRNA are used. In the wells, there are single strand DNA not RNA.

[deval]

This video has made understanding so simple, and its 7 years old yet the best video

[ruhidyusifov]

Thank you for helping by sharing you guys are brilliant.

[TheOnlyRero]

i love khan academy videos .. but some of them like this one has a very low audio i can barley hear it!

[lolacasielleslapeira]

i love you guys, this is just fantastic!

[DrFelix]

His mic is bit on the quiet side, but I've heard worse. Good explanation, thx!

[zhansayabauyrzhanova]

here is my question: how to label with yellow and blue? could u explain the mechanism of it? thank you for considering!

[Quolon]

That means the complementary sequences present in that well (which aren't labelled fluoroscently) are known to us right??

[uroojaarif]

I have a confusion about the radio labeling (yellow dots & blue dots) how is it done ? How can one know whether one is a cancer cell or normal cell in the first place ?

[FabriceTheArtist]

Great video. But, in my textbook it says that the wells are filled with DNA, not mRNA.

[Nisia]

omg it was sooo helpfull, thank you VERY much ;)

[jsantana]

In the well, would their be complementary RNA, or ssDNA complementary to the probed cDNA ?

[atti]

so is each well complementary to only 1 gene each?

[ErinRaciell]

Jesus I’m barely awake for my biotech midterm and this guys enthusiasm it’s not helping...

[kamilab]

does up regulation mean the same as duplication of a specific gene ?

[عمارالاسمري-تف]

Please try to raise your voice, Couldn't complete the list because of that!
