Stepwise Enzymatic Synthesis of the Specific C_(3')–C_(5') Internucleotide Bond

The review deals with the methods of synthesis of low-molecular-weight oligoribonucleotides based on the use of various ribonucleases and polynucleotide phosphorylase, whereby oligonucleotides can be obtained rapidly and in fairly high yields by a gradual (stepwise) growth of the oligonucleotide chain. The possibilities of this comparatively new field in the synthesis of oligonucleotides and the prospects for its development are discussed.
