And that let Marshall Nirenberg, you know, take RNA -- synthetic RNA -- put it in a system making protein. He made polyphenylalanine, polyphenylalanine. So that's the first cracking of the genetic code, and it was all over by 1966.
马歇尔·尼伦伯格也因此可以把人造RNA 放进培养系统里制造蛋白质出来。他当时合成的是 多聚苯基丙氨酸。那也算是基因密码破解的第一步， 而到了1966年，一切的密码就都已经被破解了。
