mRNA polyadenylation. 2. Formation of poly(A) tails in yeast, plant, prokaryote and virus mRNAs

M. I. Zarudnaya

The present work is the last part of the review devoted to polyadenylation of pre mRNAs from different categories of organisms. The mechanisms of poly(A) tails formation in yeast, plant, prokaryote and virus mRNAs are under consideration. A model of formation of cleavage complex, assembled on the polyadenylation site of yeast pre mRNA, is proposed.
