Polyadenylation - 새창
The addition of a tail of polyadenylic acid (POLY A) to the 3' end of mRNA (RNA, MESSENGER). Polyadenylation involves recognizing the processing site signal, (AAUAAA), and cleaving of the mRNA to create a 3' OH terminal end to which poly A polymerase (POLYNUCLEOTIDE ADENYLYTRANSFERASE) adds 60-200 adenylate residues. The 3' end processing of some messenger RNAs, such as histone mRNA, is carried out by a different process that does not include the addition of poly A as described here.
Synonyms : Polyadenylations
Polyalthia - 새창
A plant genus of the family ANNONACEAE. Members contain 8-oxopolyalthiaine.
Polyanetholesulfonate - 새창
A compound originally developed as an anticoagulant, but possessing anticomplement action and lowering the bactericidal action of blood. It is used in vitro to inhibit blood coagulation and as a diagnostic reagent to encourage the growth of pathogens in the blood. It is also used to stabilize colloidal solutions such as milk and gelatin. (From Merck Index, 11th ed)
Polyanhydrides - 새창
Anhydride polymers with a repeating structure of RC(=O)OC(=O)R. They readily hydrolyze in water making them useful for DELAYED-ACTION PREPARATIONS.
