虽然化学理论还不能支持一个工程的愿景,允许分子,DNA序列和蛋白质是可互换的部分,在人工结构没有“修修补补”,进步可以在合成生物学的挑战,在现有的理论极限。这些迫使科学家们跨越未知的领域,他们必须解决没有脚本的问题,如果理论不充分,失败的结果。因此,综合以分析无法做到的方式推动发现和范式变革。此外,如果对故障进行分析,就会出现新的理论。在这里,我们通过合成一个能够达尔文进化的人工遗传系统来说明这一点,这一特征在理论上是生命的普遍特征。
While chemical theory cannot yet support an engineering vision that allows molecules, DNA sequences, and proteins to be interchangeable parts in artificial constructs without “tinkering”, progress can be made in synthetic biology by pursuing challenges at the limits of existing theory. These force scientists across uncharted terrain where they must address unscripted problems where, if theory is inadequate, failure results. Thus, synthesis drives discovery and paradigm change in ways that analysis cannot. Further, if failures are analyzed, new theories emerge. Here, we illustrate this by synthesizing an artificial genetic system capable of Darwinian evolution, a feature theorized to be universal to life.
