    Cluster analysis has placed a group of down regulated genes in the upper left corner. In the field of molecular biology, gene expression profiling is the measurement of the activity (the expression) of thousands of genes at once, to create a global picture of cellular function. These profiles can, for example, distinguish between cells that are ...
