What goes in and out of nuclear membrane

I know mRNA and ribosome subunits come out
Can’t recall what goes in
Ocr As bio

Hi ,
So this sounds like translation to me , im a y12 student i did this a month or so ago.

So once the Hydrogen bonds have reformed after having its template strand used to produce a complementary stand ( A-T and G-C) and has been seperated by RNA polymerase (enzyme) this stand is a mRNA stand it leaves the nuclues and enters the cytoplasm and to a ribosome.

Here tRNA molecules carry amino acids to said ribosome.
These amino acids carry complementary anticodons to the mRNA strand .

*remember* here instead of A-T its A-U (Urasil) as its not DNA

tRNA molecule attaches which catalyses a peptide bond between 2 amino acids.
So the 1st tRNA molecule moves away and leaves its amino acid behind (think of it as donating the amino acid) and this repeats till a stop condon is completed.

The stand ends and the polypeptide chain moves away from the ribosome

i also do a level biology in year 12

How many chapters have you been tested on?
We have had four test
But immunity and cell divn was tested tog
Nucleus acid on its own
Enzyme on its own
Bio molecule ... I was terrible
How are you doing in your end of module tests?

THA


Thank you so much for your reply

Amazing notes
But mark scene is a so and so
It says hormones go in and ribosome and men’s can move in
I am of the opinion however much you learn if you don’t please the examiner and know the ms you are stuffed
This is so unjust
How hv you been doing in your end of module test?
Can I keep in touch with you to discuss bio topics ?
Hv you got any notes on evolution classification ?
I am struggling with biodiversity as well
My school is going at a break neck speed

I think school do topics in different orders but i have done
Enxymes , bio molecules , membranes , nucleic acids, transport in animals, proteins , meiosis and mitosis , transport in planrs , and other stuff

When would you have the AS exam?
We will hv an internal exam not the actual AS exam

We dont do AS we just do A level .

Do you have end of year 12 exam ?

I was asking about this
June exam?

Yes i believe its june. Im not sure what else i can say on it

Thanks
Are you doing EPQ?
