How does DNA function as an information storage medium?

   
I wanted to relate this topic to microarrays, but I searched and didn't find much about it.

There are a few layers to it, but basically the DNA sequence is read by proteins that transcribe the sequence into an intermediate message (mRNA). Those mRNAs are then translated by ribosomes into proteins, which then allow a cell to perform specific functions. Not all RNAs are translated, some perform functions in the cell. This movement of info from DNA->mRNA->protein is called “the central dogma” of biology.
