Question

How can microarrays help us understand cellular functions? a. Microarrays let us directly measure protein expression in individual cells. b. Microarrays let us study different cells under different conditions. c. Microarrays, by hybridizing cDNAs to DNA sequences already present on a chip, let us identify which portions of a genome were being expressing a cell at a particular time. d. Microarrays, by hybridizing DNA to cDNA sequences already present on a chip, let us identify which portions of a genome were being expressing a cell at a particular time. e. Microarrays let us identify which DNA sequences are present in a particular cell type under certain conditions.
