Explain why a eukaryotic mRNA that has begun to be degraded from the 3' end, but still has its complete coding region intact is not efficiently translated
What will be an ideal response?
Eukaryotic translation uses a closed-loop process where the 5' G cap and the 3' poly A-tail of the mRNA loop around and interact with the ribosome to initiate translation. If the 3' poly-A tail has begun to degrade then translation will not efficiently be initiated.
