The present invention is directed to methods, compositions and kits for template-free enzymatic synthesis of polynucleotides having sequences capable of forming G-quadruplex (G4) structures. In accordance with the invention elongation reactions affected by G4 formation are carried out in the presence of polyC oligonucleotides, such as polyC initiators, that inhibit or prevent formation of either intra-strand or inter-strand G4 structures.
