(2018) prepended DNA strands with specially chosen address sequences called primers and provided certain design criteria for these primers. We provide explicit constructions of error-correcting codes that are suitable as primer addresses and equip these constructions with efficient encoding algorithms.\n  Specifically, our constructions take cyclic or linear codes as inputs and produce sets of primers with similar error-correcting capabilities.
