Rationale
So much of the information that has come available to us in the past 10 years derives from genome sequences. It is important to appreciate the limitation of such information, and to that end, understanding the process by which genomes are sequenced may be helpful. We'll use as a driving force a search in the genome of Drosophila melanogaster for the gene encoding a specific protein, FMRP, related in humans to Fragile X Syndrome.
