Described herein are compositions and methods for the production and quantification of barcoded or unique molecular identifier (UMI)-labeled substrates. In one aspect, the substrate is a bead comprising a template oligonucleotide that is elongated by successive extension reactions to provide a bead with an oligonucleotide comprising a plurality of barcodes and conserved anchor regions. Methods are also described for quantifying the amount of template oligonucleotide loaded onto the substrate and the products of the extension reaction after each round and after the final extension.

Methods for production and quantification of unique molecular identifier-labeled beads

Disclosed herein are nucleic acid-based data storage systems and nucleic acid data storage constructs comprising reusable nucleic acid sequences, each representing information carried by a single bit (and, in some embodiments, one or more adjacent bits) within a bit string, and each furthermore representing the position of the single bit within the bit string. Also described are methods for storing data in the nucleic acid-based data storage systems and nucleic acid data storage constructs of the disclosure.

DNA data storage using reusable nucleic acids

The invention provides compositions and methods for amplifying nucleic acid polymer sequences in a high complexity nucleic acid sample. The unique compositions of the invention include a primer set composed of a mixture of two types of primers for DNA synthesis. For extension in one direction, the primers all contain modifications that destroy their ability to serve as templates that can be copied by DNA polymerases. For extension in the opposite direction the set includes at least one primer that can serve as a template and be replicated by DNA polymerases throughout its length. The method can be carried out by mixing the nucleic acid polymer sequence of interest with the set of DNA synthesis primers in an amplification reaction mixture. The reaction mixture is then subjected to temperature cycling analogous to the temperature cycling in PCR reactions. At least one primer in the primer set hybridizes to the nucleic acid polymer. It is preferred that the non-replicable primer hybridizes to the nucleic acid polymer and is extended to produce an extension product that contains sequence from the nucleic acid polymer to which the replicable primer then hybridizes. Of course, if the nucleic acid polymer is double stranded, both the replicable and nonreplicable primers will hybridize and be extended by DNA polymerase.

Methods for amplifying polymeric nucleic acids

The invention provides methods and compositions for the amplification and replication of nucleic acid molecules. In particular, novel amplification methods, referred to herein as polynomial amplification, are provided. According to these methods, a nucleic acid molecule to be amplified is contacted with at least two primers; a non-replicable primer which may hybridize to the nucleic acid molecule being amplified, and a replicable primer which may hybridize to a primer extension product generated from extension of the non-replicable primer.
