“After all, the resulting life forms now being discussed will still rely on a biological “chassis,” the “hollowed out” cell. As the Harvard researcher points out, “That shell is not such an empty husk — if that’s all it was, it wouldn’t work. If the empty husk is like a computer and has the basics of microprocessor and so forth … the unique thing about biology is that not only does it read the program, it also modifies the program, turning genes on and off.”
