| polyacrylamide |
Polyacrylamide is an acrylate polymer formed from acrylamide subunits that is readily cross-linked. Acrylamide needs to be handled using Good Laboratory Practices (GLP) to avoid poisoning since it is a neurotoxin. Polyacrylamide is not toxic, but un-polymerized acrylamide can be present near the polymerized acrylamide. Therefore it is recommended to handle it with caution. ...

| polyadenylation |
Polyadenylation is the covalent linkage of a polyadenylyl moiety to a messenger RNA molecule. In eukaryotic organisms, polyadenylation is the mechanism by which most messenger RNA (mRNA) molecules are terminated at their 3' ends. The poly(A) tail aids in mRNA stability by protecting it from exonucleases. Polyadenylation is also important for transcription termination, for export of the mRNA from the nucleus, and for translation. ...
