Three billion base pairs, tens of thousands of genes. As I figure it, the complete sequence of my genome would just about fit on a single CD -- without compression, about which I understand little. Imagine sending off a fleck of spit and a thousand bucks and getting back one's genome. Netflix for genes.
A template for building a Chet clone. More information than I want to know, or want anyone else to know. But not yet a Chet.
