obsolete polynucleotide adenylyltransferase activity true OBSOLETE. Catalysis of the template-independent extension of the 3'- end of an RNA or DNA strand by addition of one adenosine molecule at a time. Cannot initiate a chain 'de novo'. The primer, depending on the source of the enzyme, may be an RNA or DNA fragment, or oligo(A) bearing a 3'-OH terminal group. ATP:polynucleotidylexotransferase activity This term was obsoleted because it represents the same activity as RNA adenylyltransferase activity ; GO:1990817.
