The post-transcriptional addition of a series of adenines to the 3' end of a eukaryotic mRNA.
addition of a string of adenosine nucleotides (poly-A tail) to the 3' end of mRNAsin eukaryotic cells.
the addition of several hundred A nucleotides to the 3' ends of mRNAs
Post-transcriptional addition of multiple adenine residues to the 3' end of eukaryotic mRNA. Also called poly-(A) tailing. The adenine-rich 3' terminal segment is called a poly (A) tail.
the addition of a sequence of polyadenylic acid to the 3' end of a mRNA after transcription.
is the addition of a sequence of polyadenylic acid to the 3Â' end of an eukaryotic RNA after its transcription.
Polyadenylation is the covalent linkage of a poly(A) tail to a messenger RNA (mRNA) molecule. It is part of the route to producing mature messenger RNA for translation, in the larger process of protein synthesis to produce proteins. In eukaryotic organisms, most messenger RNA molecules end with a poly-A stretch at their 3' ends.
