of the species it was taken from, every alien cell contained the Descolada body, and the computer declared them absolutely identical in chemical proportions.
Novinha expected Pipo to nod, tell her it looked interesting, maybe come up with a hypothesis. Instead he sat down and ran the same test over, asking her questions about how the computer comparison operated, and then what the Descolada body actually did.
"Mother and Father never figured out what triggered it, but the Descolada body releases this little protein-- well, pseudo-protein, I suppose-- and it attacks the genetic molecules, starting at one end and unzipping the two strands of the molecule right down the middle. That's why they called it the descolador-- it unglues the DNA in humans, too."
"Show me what it does in alien cells."
Novinha put the simulation in motion.
"No, not just the genetic molecule-- the whole environment of the cell."
"It's just in the nucleus," she said. She widened the field to include more variables. The computer took it more slowly, since it was considering millions of random arrangements of nuclear material every second. In the reed cell, as a genetic molecule came unglued, several large ambient proteins affixed themselves to the open strands. "In humans, the DNA tries to recombine, but random proteins insert themselves so that cell after cell goes crazy. Sometimes they go into mitosis, like cancer, and sometimes they die. What's most important is that in humans the Descolada bodies themselves reproduce like crazy, passing from cell to cell. Of course, every alien creature already has them."
But Pipo wasn't interested in what she said. When the descolador had finished with the genetic molecules of the reed, he looked from one cell to another. "It's not just significant, it's the same," he said. "It's the same thing!"
Novinha didn't see at once what he had noticed. What was the same as what? Nor did she have time to ask. Pipo was already out of the chair, grabbing his coat, heading for the door. It was drizzling outside. Pipo paused only to call out to her, "Tell Libo not to bother coming, just show him that simulation and see if he can figure it out before I get back. He'll know-- it's the answer to the big one. The answer to everything."
"Tell me!"
He laughed. "Don't cheat. Libo will tell you, if you can't see it." "Where are you going?"
"To ask the piggies if I'm right, of course! But I know I am, even if they lie about it. If I'm not back in an hour, I slipped in the rain and broke my leg."
