大约2年多以前，Biorad（伯乐）公司为了宣传推广其新产品，创作了下面这个PCR之歌。听了好几遍，每次都觉得蛮有意思的。PCR (polymerase chain reaction, 聚合酶链式反应），是一种特异性DNA序列体外引物定向酶促扩增技术，这项技术的发明对生物学的发展具有划时代的意义。想了解等多有关PCR的知识，可以查看聚合酶链式反应(百度百科，中文）或Polymerase chain reaction（维基百科，英文）
不多说了，看视频，听歌！
如果你懂了，英文肯定相当的牛逼！听不懂比较正常，下面是歌词：
PCR之歌歌词
The PCR Song
There was a time when to amplify DNA,
You had to grow tons and tons of tiny cells.
Then along came a guy named Dr. Kary Mullis,
Said you can amplify in vitro just as well.
Just mix your template with a buffer and some primers,
Nucleotides and polymerases, too.
Denaturing, annealing, and extending.
Well it’s amazing what heating and cooling and heating will do.
PCR, when you need to detect mutations.
PCR, when you need to be recombine.
PCR, when you need to find out who the daddy is.
PCR, when you need to solve a crime.
