Abstract

Purified nucleic acid encoding a yeast, human, or bovine poly(A) polymerase, where the bovine nucleic acid consists essentially of that nucleic acid sequence shown as nucleotide SEQ. ID. NO.: 1; the resulting recombinant poly(A) polymerase expressed from these nucleic acids, corresponding methods of their production, and methods of use of the poly(A) polymerase.
