Polyadenylation
Polyadenylation is a process in which a chain of adenine (A) nucleotides is added to the 3’ end of messenger RNA (mRNA) molecules. This process is essential for the correct functioning of eukaryotic gene expression, as it facilitates the transport of mRNA molecules into the cytoplasm for translation into proteins. By adding a polyA tail, mRNA molecules are protected from being degraded and this ultimately increases their stability and longevity. In addition, the added A-tracts also help the ribosome to recognize the start and end of the target gene. Polyadenylation is thus an important step in gene expression and the proteins produced are essential for the normal functioning of a cell.

DNA, is like a blueprint of biological guidelines that a living organism must follow to exist and remain functional. RNA, helps carry out this blueprint's guidelines. RNA is more versatile than DNA, capable of performing numerous, diverse tasks in an organism, however DNA is more stable and holds more complex information for longer periods of time.
