摘要

In May 2010, the richest, most powerful man in biotechnology made a new creature. J. Craig Venter and his private-company team started with dna and constructed a novel genetic sequence of more than one million coded bits of information known as nucleotides. Seven years earlier, Venter had been the first person in history to make a functioning creature from information. Looking at the strings of letters representing the dna sequence for a virus called phi X174, which infects bacteria, he thought to himself, "I can assemble real dna based on that computer information." And so he did, creating a virus based on the phi X174 genomic code. He followed the same recipe later on to generate the dna for his larger and more sophisticated creature. Venter and his team figured out how to make an artificial bacterial cell, inserted their man-made dna genome inside, and watched as the organic life form they had synthesized moved, ate, breathed, and replicated itself.

Craig Venter)和他的私人公司团队从dna开始,构建了一个新的遗传序列,该序列包含超过一百万个称为核苷酸的信息编码位。七年前,Venter是历史上第一个根据信息制造出运转正常的生物的人。他看着代表感染细菌的一种名为phi X174的病毒的dna序列的字母字符串,他自己想:“我可以根据该计算机信息来组装真正的dna。”因此,他做到了,并根据phi X174基因组代码创建了一种病毒。后来,他遵循相同的配方为他的更大,更复杂的生物生成了dna。 Venter和他的团队研究了如何制造人造细菌细胞,将其人造dna基因组插入其中,并观察了他们合成的有机生命形式如何移动,饮食,呼吸和自我复制。
