Abstract excerpt
Cleavage and polyadenylation of eukaryotic mRNA requires efficiency and positioning elements in the 3'-untranslated region (3'-UTR) of the mRNA. Specific point mutations were introduced into the yeast GCN4 3'-UTR to detect sequence motifs which are involved in the positioning of the poly(A) site. 3'-End proces-sing activities of different GCN4 3'-UTR alleles were measured in an in vivo test system. Point...
