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 ...

DNA microarray chips enable the parallel investigation of a given sample concerning the presence and amount of specific DNA sequences within that sample. Whereas today such chips utilize optical ...

The human genome project was undertaken to determine the human DNA sequence and analyze variation among individuals. To make use of this information, tools were developed that could collect and ...
