Abstract
This disclosure describes techniques to improve the accuracy of random access of data stored in polynucleotide sequence data storage systems. Primers used in polynucleotide sequence replication and amplification can be scored against a number of criteria that indicate the fitness of sequences of nucleotides to function as primers. Primers having scores that indicate a particular fitness to function as primers can be added to a specific group of primers. The primers from the group of primers can be used in amplification and replication of polynucleotide sequences that encode digital data. Additionally, an amount of overlap between primer targets and payloads encoding digital data can be determined. Minimizing the amount of overlap between primer targets and payloads can improve the efficiency of polynucleotide replication and amplification. The bits of the digital data can be randomized to minimize the amount of overlap between payloads encoding the digital data and primer targets.
