Microarray technology allows for the parallel and high-
throughput analysis of gene expression present in a biological
sample, as reflected in the relative amounts of mRNA
transcripts. The development of this “genomic” technology was
fostered by the Human Genome Project (1990-2003), and the
explosive growth in available sequence data in databases like
GenBank. This data has been used to manufacture microarrays in a
process likened to downloading sequence databases onto chips. A
short PowerPoint presentation illustrating the basic principles
of microarrays is available for download. - Educational
