After Translation

Translation

Best Answer OldCloner, 08 January 2019 - 06:42 AM

Hello again,

 

I think you mean after transcription, how does the RNA strand get to the ribosome?  Since you have an interest in the whole process, you might find the numerous You Tube videos and educational diagrams on the internet very useful.  I found one that is pretty good for explaining in fairly basic terms the process from transcription through translation, so you don't have to keep asking separate questions. But it does have a fair amount of detail. The link is below, but once you get to that one you will be able to see many similar videos that may be better or not as good, depending on your point of view. You will at least be introduced to many ways of teaching this subject.

 

I was not able, however to find an answer to exactly how the mRNA is transported out of the nucleus, other than it passes through a pore in the nuclear membrane. If there is an active transport for this, I am not aware of it- maybe another expert can help with that question.  It may be an area of relatively new research, as we are always learning new details about how cells actually work.

 

 

 

I hope this helps with your search for knowledge.

Hi,

 

          After translation, how does the RNA strand get to the ribosome? What is the name of the enzyme it is guided by?

 

Thanks

Hi again,

I found some more information on your topic. Credit Oregon State University with this one:

 

How are RNAs transported from the nucleus?

Most RNAs go out of the nucleus, rather than coming into it. RNAs are generally transported as RNA-protein complexes, in which the proteins carry the nuclear export signals. Just as for proteins, alone, these complexes are recognized and bound by exportins and escorted out of the nucleus by Ran/GTP.
-Ribosomal RNAs are a special case, in that they are assembled with ribosomal proteins into ribosomal subunits before being exported from the nucleus.

 

If you want another video, try this one:
