    • Cytidine-rich templates effectively facilitate oligonucleotide synthesis.
    • Nucleotide incorporation is dependent on complementary base presence in the template.
    • The reaction exhibits high fidelity, yielding products with mean chain lengths of 6-10 nucleotides.
    • Specific base incorporation patterns were observed, with limitations at the 5' termini for non-guanosine bases.

    Conclusions:

    • Polynucleotide templates, particularly those rich in cytidine, are effective tools for template-directed oligonucleotide synthesis.
    • The method provides a high-fidelity route to short oligonucleotides.
    • Understanding base incorporation patterns is key for optimizing synthetic strategies.
