Abstract
The present disclosure relates to methods, processes and systems for enzymatic synthesis of oligonucleotide from a single-stranded, immobilized primer in the presence of a polymerase. Using the disclosed methods single-stranded oligonucleotides can be synthesized enzymatically from a single-stranded, immobilized primer in the presence of deoxyribonucleotide triphosphates or ribonucleotide triphosphates. Dideoxyribonucleotide triphosphates, deoxyribonucleotide triphosphates with reversible terminators, or ribonucleotide triphosphates with reversible terminators can be added enzymatically to the end of the primer or its extension products. According to the disclosed method, a single-stranded primer can bind to a template such that the thus-formed double-stranded structure can allow the polymerase to extend the primer at 3′ end.
