KEY PARAGRAPH: "M. pneumoniae has just one-fifth as many genes as E. coli, the traditional single-cell model organism. That makes it an ideal target for systems biologists who want to understand how cells function. To them, genome scans are just a first step. They don’t explain when or why genes are turned on and off, or how different genes interact at different times, or how cellular “machines” use proteins produced by gene instructions."
