In Regards to MRNA Stability,what is the Effect of Decapping

Question

In regards to mRNA stability,what is the effect of decapping enzymes? A)The m⁷G cap of mRNAs is removed causing mRNAs to be degraded from the 5' end. B)The splicing of mRNAs is blocked,which destabilizes mRNAs. C)The m⁷G cap of mRNAs is stabilized allowing mRNAs to be protected at the 5' end. D)The polyadenylation of mRNAs is stabilized allowing mRNAs to be protected at the 3' end. E)The polyadenylation of mRNAs is removed and mRNAs are degraded from the 3' end.

Accepted Answer

Decapping enzymes remove the m⁷G cap from the 5' end of mRNAs, which destabilizes them and causes them to be degraded from the 5' end.
