The brain is not an electronic device. An EMP is basically a large amount of electrons flying by all at once. They are negatively charged, and as they pass by they distort your local EM-field (hence the name). This distortion induces current in the wires (a phenomenon known since Faraday) - since most wires aren't made with a large tolerance, the sudden ...

http://en.wikipedia.org/wiki/Electromagnetic_pulse mentions the following natural sources of EMP, which I have ordered by frequency / period, from the shortest to the longest: Electrostatic discharge from objects coming into contact (normally too small to be of any concern) Lightning (milliseconds) Solar flares (hours.) Such flares cause geomagnetic storms ...

No — typical DNA extraction will not preserve information about the biochemical state of the cell. During the process of DNA extraction, proteins are removed and DNA from a population of cells gets precipitated. Then you dissolve the DNA. In this process native conformational state cannot be preserved. However there are techniques (see this post) that ...
