Publication number: 20210147833Abstract: A method includes grafting oligonucleotides to a flow cell and preparing a library of polynucleotides. Each polynucleotide has been written to contain retrievable information and includes a region complementary to one of the sequencing initiation primers grafted to the flow cell. Each polynucleotide is indexed to permit discrete identification of that polynucleotide and the information it contains over other polynucleotides in the library. Another method includes writing two polynucleotides including two sequences with reverse complementary joining sequences onto a flow cell. One of the polynucleotides is extended to generate a third polynucleotide comprising a sequence that is the combination of the first and second sequences.
