DNA microarray analysis is the most appropriate technique for testing the hypothesis that humans and chimps differ in the expression of a large set of shared genes. This technique allows for the comparison of gene expression levels between two different organisms and can identify differences in expression patterns. PCR is a technique used to amplify DNA sequences and would not be appropriate for comparing gene expression between two different organisms. DNA sequencing would provide information about the nucleotide sequence of the genes but would not provide information about gene expression levels. Protein-protein interaction assays would provide information about how proteins interact with each other but would not provide information about gene expression levels.
