AB As the Human Genome Project and related efforts identify and determine
the DNA sequences of human genes, it is important that highly reliable
and efficient mechanisms are found to access individual genetic
variation. It is only through a greater understanding of genetic
diversity that the true benefit of the Human Genome Project will be
realized. One approach, hybridization to high-density arrays of
oligonucleotides, is a fast and effective means of accessing this
genetic variation. Light-directed chemical synthesis has been used to
generate miniaturized, high-density arrays of oligonucleotide probes.
Application-specific oligonucleotide probe array designs have been
developed for the rapid screening of characterized genes. Dedicated
instrumentation and software have been developed for array
hybridization, fluorescence detection and data acquisition and analysis.
In a specific and challenging application, oligonucleotide probe arrays
have been used to screen the reverse transcriptase and protease genes of
the highly polymorphic HIV-1 genome to explore genetic diversity and
detect mutations conferring resistance to antiviral drugs. Results from
this application strongly suggest that oligonucleotide probe arrays will
be a powerful tool for rapid investigations in sequence checking,
pathogen detection, expression monitoring and DNA molecular recognition.
