"I should put that in scare quotes," Moira said, reaching up with both hands and crooking her fingers. "Obviously I’m not literally using my hands. But with the equipment in there"—she tossed her head in the direction of the lab—"I can isolate a cell—a sperm or an ovum—and read its genome. I’m skipping over a lot of details, obviously. But the point is that I can get a digital record of its DNA. Once that’s in hand, it turns into a software exercise—the data can be evaluated and compared to huge databases that shipped up as part of the lab. It’s possible to identify places on a given chromosome where a bit of DNA got damaged by a cosmic ray or radiation from the reactor. It is then possible to repair those breaks by splicing in a reasonable guess as to what was there originally."
