1. A method for processing messenger ribonucleic acid (mRNA) molecules from a single cell, comprising:
- (a) partitioning a plurality of cells and a plurality of beads in a microwell array comprising a plurality of wells, wherein a well of said plurality of wells comprises said single cell from said plurality of cells and a single bead from said plurality of beads, and wherein said single bead comprises nucleic acid barcode molecules each comprising a common barcode sequence;
(b) in said well comprising said single cell and said single bead, releasing messenger ribonucleic acid (mRNA) molecules from said single cell, wherein upon release from said single cell, said released mRNA molecules attach to said nucleic acid barcode molecules;
(c) subjecting said released mRNA molecules attached to said nucleic acid barcode molecules to reverse transcription to yield complementary deoxyribonucleic acid (cDNA) molecules each comprising said common barcode sequence or a complement thereof; and
(d) subjecting said cDNA molecules to one or more reactions to generate a set of nucleic acid molecules for nucleic acid sequencing.

49. A method for processing messenger ribonucleic acid (mRNA) molecules from single cells, comprising:
-
(a) partitioning a plurality of cells and a plurality of beads in a microwell array comprising a plurality of wells, wherein said plurality of wells comprises 1,000 occupied wells, each occupied well of said 1,000 occupied wells comprising a single cell of said plurality of cells and a single bead of said plurality of beads, and wherein said single bead comprises nucleic acid barcode molecules comprising (i) a common barcode sequence capable of identifying said single cell and (ii) a capture sequence, wherein said common barcode sequence is different for different occupied wells of said 1,000 occupied wells; (b) releasing messenger ribonucleic acid (mRNA) molecules from single cells of said 1,000 occupied wells, wherein released mRNA molecules in each occupied well of said 1,000 occupied wells are captured by said nucleic acid barcode molecules via said capture sequence subsequent to release; (c) subjecting said released mRNA molecules in each occupied well of said 1,000 occupied wells to reverse transcription to yield complementary deoxyribonucleic acid (cDNA) molecules comprising said common barcode sequence or complement thereof; and (d) subjecting cDNA molecules or derivatives thereof generated in each occupied well of said 1,000 occupied wells to one or more nucleic acid amplification reactions to generate a set of barcoded nucleic acid molecules for nucleic acid sequencing. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
