everyones so rude about her accent. she explained everything beautifully, this is FREE education on the internet. take it or leave it.

@tahsinuddin Жыл бұрын

She problem for me isn't her accent (her voice sounds fine) but that she only describes concepts in words instead of actually showing them out. Sal and the other MCAT guy do a much better job of actually drawing out the processes they discuss instead of just describing them in words (and only writing the words out). I wish she would actually show how the 5' cap, 3' tail, and RNA editing work instead of just describing them in words because that's the whole reason I'm watching a video on the topic

You can also remember that the poly A tail goes on the 3' end if you just think of "AAA" (triple-a),... easy to remember that way :)

This video extensively goes through all the parts of gene transcription accurately AND it even reviews/defines terms along the way! It doesn’t matter her voice, what matters is the information!

I'm currently studying biology in my final year of school and my textbook made me want to cry, but this saved my brain - thank you so much for this video.

Total bullshitter! How much she paid you to say that?

This vidoe is based on POST-transcriptional modification not the actual regulation of the processes...

The 5' cap is added before the splicing, not after.

Amazing how relevant this has become in light of the new Covid-19 vaccine 💉.

@lorcanmarkus8181 5 жыл бұрын

the way my ap bio teacher taught me how to remember the difference between introns and exons is EXons are EXpressed. introns you just gotta remember as the nonexpressed mRNA lol.

Introns are intruding

*Introns are INterrupting* the Transcription of mRNA so need to be cleaved out~

how poly A helps in trancription termination

@arham8441 Жыл бұрын

That is poly u tail which helps in transcription termination as the u-a base interactions bw the dna and new synthesized rna are weak and so the rna is liberated

The way she speaks makes it sound like she's annoyed that she has to teach this topic.

Intron is the one that leave, not the exon!

@esem1367 4 жыл бұрын

alberto tamayo only exons become mRNA, mRNA leaves the nucleus into the cytoplasm, so yes the exons do leave. Perhaps you are thinking introns leave the strand, in that case it is correct.
