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

question 5

Multiple Choice

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.
