What RNA Modification is Important for MRNA Stability

Question

What RNA modification is important for mRNA stability?
A) alternative splicing
B) RNA editing
C) base modification
D) 3' polyA tailing
E) processing

Accepted Answer

3' polyA tailing is the addition of a long chain of adenine nucleotides to the 3' end of mRNA, which plays a role in protecting mRNA from degradation by nucleases. This modification increases mRNA stability and promotes efficient translation.
