Background
Adds poly(A) tail to the 3' end of many RNAs, which usually targets these RNAs for decay. Plays a significant role in the global control of gene expression, through influencing the rate of transcript degradation, and in the general RNA quality control. Rho-independent transcription terminators may serve as polyadenylation signals. Seems to be involved in plasmid copy number control.
