Gene Expression Analysis and DNA Microarray Assays

If we want to understand a biological organism, we turn to the expression of its genome. Which genes are being expressed, and in which cells, and when? How does this differ between a normal cell and a cancer cell? We have incredibly sophisticated techniques to investigate these questions, and the most indispensable is the DNA microarray assay. This apparatus is even more useful than it is colorful, so let's see how this works now.
