生物化学家将这套系统称之为中心法则(central dogma)：以长链核酸聚合物形式存在的DNA是遗传物质，它储存着每种蛋白质设计的数据记录。
Biochemists call it the central dogma: Genetic material, in the form of a long nucleic acid polymer called DNA, stores a digital record of every protein's design.
一旦核酸-蛋白质操作系统形成，就不可能通过进化来“修补”成其他的系统，因为这种“修补”的后果会十分严重。
Once the nucleic acid-amino acid operating system came into existence it could never be "fixed" into anything else by evolution, because the immediate consequences would have been so serious.
