Blogging the Human Genome

By the early 1960s Tie Club members and other scientists had puzzled out how DNA and RNA could make proteins, and had confirmed that the same basic DNA-to-RNA-to-protein process ran every living thing on earth: guinea pigs, E. coli, frogs, tulips, slime molds, U.S. Congressmen, whatever. But again, knowing how the process worked in general told biologists only so much: They?d discovered how to build proteins in general, but not what kinds of proteins a life form actually did build. For that, they had to start sequencing genes?that is, determining the order of a creature?s As, Cs, Gs, and Ts.
