title: Specific oligoribonucleotide synthesis using primer-independent polynucleotide phosphorylase.
abstract: Oligoribonucleotides of a predetermined base sequence beginning with adenylyl-3', 5'-adenosine at the 5' end have been synthesized in yields varying between 13% and 42%. The synthesis was carried out using primer-independent polynucleotide phosphorylase from E. coli in the presence of high concentrations of primer and of sodium chloride.
