| Next came DNA microarrays that measured thousands of genes simultaneously. Chen's work involves DNA microarrays or gene chips-a technology that monitors the whole genome on a single chip so that researchers can have a better picture of the interactions among thousands of genes simultaneously. The developing complementary technologies of DNA microarrays and proteomics are allowing the response of bacterial pathogens to different environments to be probed at the whole genome level. |
