UTRs can play a role in...?

Post by Asynja » Sat Jan 10, 2009 5:07 pm

Hello! I am trying to answer the following question:

Untranslated regions of eukaryotic mRNA are known in some cases to play a role in:
A. Regulated mRNA degradation.
B. Transcription initiation.
C. Assembly of ribosomes.
D. Termination of translation.

I don't think it's A or C. However, I thought the 5' UTR helped with initiation, and I thought the poly-A tail helped with termination...

Ah can someone please help? Is the answer B or D or both?!
