complete genomic sequences in ever-shorter intervals, experimental procedures for
elucidating the cellular effects and consequences of the DNA-encoded information
become critical for further analyses. In recent years, DNA microarray technology
has emerged as a prime candidate for the performance of many such functional
assays. Technically, array technology has come a long way since its conception some
15 years ago, initially designed as a means for large-scale mapping and sequencing.</p> <p>The basic arrangement, however, could be adapted readily to serve eventually as an
analytical tool in a large variety of applications. On their own or in combination
with other methods, microarrays open up many new avenues of functional analysis.</p>
