For microarray analysis, several hundred to millions of DNA oligonucleotides are placed on a small piece of glass, a filter, or a silicon slide. These oligonucleotides, called probes, are bonded to the substrate by a chemical. Usually the DNA is focused on several specific genes, which are lined up by number, or type. This task is performed by a robot due to its precise requirements and microscopic size. Testing on the genes can be performed simultaneously. The genes of interest are often... więcej
