Type of tail that protects mRNA?

Explanation:
In eukaryotic cells, mRNA gets a tail made of many adenine nucleotides at the 3' end, called the poly-A tail. This tail protects the transcript by blocking degradation from 3' exonucleases, which helps the mRNA stay intact longer. It also aids in exporting the mRNA from the nucleus and works with the poly(A)-binding protein to help recruit the translation machinery, improving translation efficiency. The other nucleotide repeats listed aren’t the natural protective tail for cellular mRNA, and a poly-A tail uniquely provides this stability and translational boost.
