Gene chips are a way of automating experiments that previously could only be done one at a time. They are a picture of what the RNA looks like at one particular moment. Thousands of DNA pieces in genes are spotted on a small surface enabling us to look at changes in gene expression profile of thousands of genes in one experiment. By comparing tissue from ALS patients with tissue from controls we can discover which genes vary their expression level in the disease.
