Polyadenylation is defined as the addition of poly (A) to messenger RNA. This tail is made up of several adenosine monophosphates (adenine bases). In eukaryotes, polyadenylation is part of the process in which messenger RNA is formed for subsequent translation. Therefore, it is part of the process of gene expression.
