For biologists, DNA microarrays present at once unprecedented opportunities and monumental challenges. In the opportunities column, microarrays produce genome-wide gene expression snapshots, ...

Comparative genomic hybridization (CGH) was developed to identify pathogenic DNA copy-number changes (e.g., duplications, deletions) on a genome-wide scale, and to map these changes to genomic ...

Launched in 1990, The Human Genome Project was a monumental effort to sequence and analyze the entire human genome to understand how genetics influence health. While the Human Genome Project helped ...

As a graduate student, Eric Olson learned something about DNA microarrays: Biochip data management can be vexing. His graduate adviser abandoned a number of microarray experiments because it was too ...
