DNA microarrays are commonly used to genotype ... on the array as the orderly arrangement of spotted samples on a solid structure provides an easily determined location for each gene being analyzed.

The history of microarrays follows a path that links the groundbreaking discovery of the structure of DNA to contemporary studies of genetics. After the first description of the double helix DNA ...

Students model how scientists use DNA microarrays to determine levels of gene expression in breast cancer patients, and then choose treatments based on what they learn. Normal-functioning DNA ...

One way they do this is to use a DNA microarray to determine the expression levels of genes. When a gene is expressed in a cell, it generates messenger RNA (mRNA). Overexpressed genes generate ...

"We believe this technique could revolutionize the use of DNA microarrays for both research and diagnostics." Groves, who is also a Howard Hughes Medical Institute (HHMI) investigator, and members ...
