The Poly-A tail is a polyadenylate sequence which is added to the 3' terminus of a eukaryotic mRNA during RNA processing. A Poly-A tail can consist up to 200 nucleotides of adenosine monophosphate, which greatly increases the stability of the mRNA. Before the addition of the Poly-A tail, the 3' terminus of a eukaryotic mRNA has been modified by exonuclease digestion.This allows the mRNA sequence to act as a substrate for the extension of Poly-A tail[1].
