the results of the hydrolysis of 4 s ( ado5 ' p ) n and ( ado3 ' p ) n by the exoribonuclease with or without alkaline phosphatase and the inhibition of the enzymatic activity by oligonucleotides having a 3'-phosphate group in the 3'-terminus suggested that the degradation proceeds in the 3 ' to 5 ' direction .
