One question: right after 1;00 ribosomes translate miRNA, if I'm right, but what is the purpose of these polypeptides? English is not my mother tongue hence it's a bit difficult to understand such scientific English, I'd be really glad if someone should elucidate my question a bit.
in 1:00 - 1:12 she is not describing the translation of the mRNA at all. she is just saying that miRNA is involved with the RNAi. what is in the picture is a way from what she is talking about. 1:12 - 1:34 is all about the function of RNAi in Algae, worms, flies, planets and culture insect cells. (NOT related to what is in the picture "protein synthesis")
From what I understand: As foreign mRNA enters the cell (like a virus injects it in the cell), dicer cuts the foreign RNA turning it into siRNA and forms a complex /w Argonaut (big part) + peewee (little part- biologists have bad humor) to make RISC which then uses the siRNA as a template to bind to other foreign mRNA and cuts it. This is then recognized by the cell and digested. RDRP takes the smaller piece, cuts with dicer and serves as a primer for MORE of the target or can be used for RISC.
xcellent video!

The voice is too monotone. Try getting a more interesting "narrator".

RISC : RNA induced Silencing Complex, and not RNA interference Silencing complex you dummy !!!!!!
