ABSTRACT
Microarrays for measuring the expression profile of cells under different developmental or environmental stages are gaining rapid acceptance by biologists as a popular method to conduct whole genome biological studies. This is especially promising given that many genomes of varying sizes have recently been sequenced, including some large genomes like Drosophila [1], Arabidopsis [31, 35, 7], human [27, 50], mouse [53] and rice [17, 56]. Soon additional large genomes such as maize [13], rat [49], chicken [41] and dog [25] may become available as well.
