Abstract

The present disclosure provides compositions, methods, systems, and devices for polynucleotide processing. Such polynucleotide processing may be useful for a variety of applications, including polynucleotide sequencing.

First claim

1. A method of nucleic acid sequence analysis, comprising:
(a) fragmenting a first nucleic acid molecule to provide a plurality of polynucleotide molecules;
(b) partitioning the plurality of polynucleotide molecules of the first nucleic acid molecule into a plurality of separate partitions, wherein each of the plurality of separate partitions comprises:
i. at least 20 polynucleotide molecules from the plurality of polynucleotide molecules, the at least 20 polynucleotide molecules comprising non-overlapping fragment polynucleotide molecules; and
ii. a plurality of barcode molecules, wherein each barcode molecule within a given partition shares a common barcode sequence and is associated with a bead within the partition;

(c) after (b), generating barcoded fragment molecules from the at least 20 polynucleotide molecules and plurality of barcode molecules within each of the separate partitions; and
(d) analyzing the barcoded fragment molecules generated in (c), thereby analyzing a nucleic acid sequence of the first nucleic acid molecule.

2. The method of claim 1 , wherein each of the plurality of separate partitions comprises at least 50 polynucleotide molecules, the at least 50 polynucleotide molecules comprising non-overlapping fragment polynucleotide molecules.

3. The method of claim 1 , wherein each of the plurality of separate partitions comprises at least 100 polynucleotide molecules the at least 100 polynucleotide molecules comprising non-overlapping fragment polynucleotide molecules.
