Nucleases Are Enzymes That Degrade MRNA

Nucleases are enzymes that degrade mRNA. In order for nuclease to overcome the inherent protections in mRNA that prevent its degradation nucleases must use

A) 5' decapping enzymes.
B) A and U sites that promote removal of the poly A tails.
C) C and G recognition sites that activate removal of poly A tails.
D) 3' end recognition sites that initiate quick degradation.
E) 3' cap and poly A tail sites that activate degradation.
