Hi Sir, At the beginning you said DNA Helicase separates DNA strands, but in the CGP textbook it says RNA Polymerase separates them as well as joins them together?
I use the terms that the mark schemes use to get the marks, on the recent papers they have credited DNA Helicase and not RNA polymerase as breaking the H-bonds so that's why I include those details in my course. FYI the books are full of things like this that are not the right choice of words to get full marks on the exam.
I'm not sure if that's a question or not but I'll tidy up your wording for how to use it in the exam... the DNA the unwinds in both transcription and in DNA replication (by DNA Helicase) but different enzymes that form the new polymer of mRNA (RNA Polymerase) and DNA (DNA Polymerase)
I think I now know what you're asking. The text books don't match the mark schemes here and the mark schemes are the things to trust (if you want to get the marks)!

Mottram Michelle you can think of it as if prokaryotes have no introns so they only have exons. So they don’t go through splicing as their mRNA is already mature.
You're a hero btw
you made something so hard, so easy to understand thank u!!
Hey can u do a video on meiosis plz
Hey Brad - I've already made a video on meiosis (and every other topic in the new spec)! You can check it out totally free from our website.
Thank you!

Just wanna let you know your doing great work brother
Cheers Adam! Much appreciated
Its RNA polymerase that unwinds in protein synthesis and DNA helices in DNA replication

Isn't it RNA Helicase which separates DNA strands rather than DNA Helicase??

After the process of splicing shouldint the addition of the guanine cap and the poly a tail take place?
Not in the world of A-Level biology! That won't be in the exam so don't worry about it for now
heh guys and dolls. lol, cheers for this
My pleasure!
i loveyou
400th like lessgo'
you mean prokaryotes have no introns REMOVED thus no splicing??
