1. A method for generating a sequencing set for nucleic acid sequencing, comprising:

  • (a) bringing an aqueous fluid comprising a plurality of cells and a plurality of beads in contact with a continuous phase comprising an oil that is immiscible with said aqueous fluid, to generate a plurality droplets, wherein a given droplet of said plurality of droplets comprises a single cell from said plurality of cells and a single bead from said plurality of beads, and wherein said single bead comprises nucleic acid molecules each comprising a common barcode sequence;

    (b) in said given droplet, subjecting messenger ribonucleic acid (mRNA) molecules from said single cell to reverse transcription in the presence of said nucleic acid molecules to yield complementary deoxyribonucleic acid (cDNA) molecules comprising said common barcode sequence;

    (c) breaking said plurality of droplets, thereby releasing a plurality of cDNA molecules from said plurality of droplets, wherein said plurality of cDNA molecules comprises said cDNA molecules or derivatives thereof; and

    (d) subjecting said plurality of cDNA molecules to one or more reactions to generate said sequencing set.
