Here we present a method for the fabrication of microarrays in which presynthesized oligonucleotides are ejected onto a glass surface by a Bubble Jet printing device. The oligonucleotides are then ...

In each type of cell, like a muscle cell or a skin cell, different genes are expressed (turned on) or silenced (turned off). If the cells that are turned on mutate, they could—depending on what role ...

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 codes ...
