Well, as an introductory video this a good one. Having said that, mRNA processing is assumed to be a co-transcriptional process, which means that splicing (for instance) occurs during transcription. This video suggests that only AFTER transcription the splicing takes place, which is not the current view....
splicing does not occur for the direct purpose of mature mRNA being able to leave the nucleus in eukaryotes. The reasons introns exist is so that cells can take advantage of an exponential number of mRNA codon combinations, allowing you to be able create a greater number of polypeptides then your genes directly code for. That is why it occurs in higher organisms and not in prokaryotes.
What do the specific colored proteins represent? I am aware that there are many subunits including U1, U4/6, BBP, but not sure what the role of each is, particularly in this animation.
@b3rangler Mumbo jumbo... spitting out random like terms in no apparent actual way of making sense and with the attended effect to confuse ppl into believing ur smart doesn’t make it so...
Very nice and clear presentation. It should also be noted however that we're dealing with eukaryotic mRNA here.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
My humour is broken, this made me laugh outloud at 2 am before today's cell bio exam
@ youre welcome
totally forgot i even commented this
Covid-19: I am inevitable
mRNA: I've waited my entire life for this
virtual cell is just the best thing on youtube EVER!
I love my textbooks, but this is such a better learning aid...

this was perfect thanks! subbed
Piccolo: NEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEERRRRRRRRRRRRRRRRRRRRDDDDDDDDD!!!!
tnx u so much i have exam after 5 hours and now i understand it very well
I think half of the views of this video are mine! 😂 I have watched this so many times!
Thanks for sharing all the vidios i knew i lifttle about plants and cloar fill thats all
nice simple video, i can visualize it better now, thanks...
HELPING ME TO PASS MY DEGREE.

what exactly happens after the poly a polymarase binds with the m rna ?
Yay thanks for this video. Helps a lot.
this is helpful for medical school lol
great vid ....thanks.......
The people who save your life when you get sick care ;)
This doesn't explain introns though
Does the processing only happen for mRNA?
thanks . that what can open the emagination to understand this science
total life saver!!! your saving me from failing my degree!!!!! :@ ahahaha
does the U on mRNA pair with a T or an A on the anti-codon
A
YASSSSSSSS LET'S STUDYY
Simple and clear! :)
Not accurate to me
This takes my biotech book 20 pages to "explain"... When will books die as a medium?! :P
@Danelawz thanx
what the hec is a cleavage factor we never studied that?? plz explain
Anyone else here in 2022?
helped a lot !!!
thanx! That was helpfull :D
BioE 10 was here
Good
Great
holy cow was this helpful :)
what the fuck just happened
Who else here from monash med watching…
